Graceful asynchronous programming with Promises - Learn web development
essentially, a promise is an object that represents an intermediate state of an operation — in effect, a promise that a result of some kind will be returned at some point in the future.
... there is no guarantee of exactly when the operation will complete and the result will be returned, but there is a guarantee that when the result is available, or the promise fails, the code you provide will be executed in order to do something else with a successful result, or to gracefully handle a failure case.
... generally, you are less interested in the amount of time an async operation will take to return its result (unless of course, it takes far too long!), and more interested in being able to respond to it being returned, whenever that is.

Useful string methods - Learn web development

Using the Web Speech API - Web APIs
speech recognition speech recognition involves receiving speech through a device's microphone, which is then checked by a speech recognition service against a list of grammar (basically, the vocabulary you want to have recognised in a particular app.) when a word or phrase is successfully recognised, it is returned as a result (or list of results) as a text string, and further actions can be initiated as a result.
... the web speech api has a main controller interface for this — speechrecognition — plus a number of closely-related interfaces for representing grammar, results, etc.
...we also set a few other properties of the recognition instance before we move on: speechrecognition.continuous: controls whether continuous results are captured (true), or just a single result each time recognition is started (false).

... chaining a common need is to execute two or more asynchronous operations back to back, where each subsequent operation starts when the previous operation succeeds, with the result from the previous step.

Using microtasks in JavaScript with queueMicrotask() - Web APIs
generally, it's about capturing or checking results, or performing cleanup, after the main body of a javascript execution context exits, but before any event handlers, timeouts and intervals, or other callbacks are processed.
... the main reason to use microtasks is simply that: to ensure consistent ordering of tasks, even when results or data is available synchronously, but while simultaneously reducing the risk of user-discernible delays in operations.
...consider code such as this: customelement.prototype.getdata = url => { if (this.cache[url]) { this.data = this.cache[url]; this.dispatchevent(new event("load")); } else { fetch(url).then(result => result.arraybuffer()).then(data => { this.cache[url] = data; this.data = data; this.dispatchevent(new event("load")); }); } }; the problem introduced here is that by using a task in one branch of the if...else statement (in the case in which the image is available in the cache) but having promises involved in the else clause, we have a situation in which the order of o...

Making asynchronous programming easier with async and await - Learn web development
this can be put in front of any async promise-based function to pause your code on that line until the promise fulfills, then return the resulting value.
...instead of needing to chain a .then() block on to the end of each promise-based method, you just need to add an await keyword before the method call, and then assign the result to a variable.

NaN - MDN Web Docs Glossary: Definitions of Web-related terms
nan (not a number) is a numeric data type that means an undefined value or value that cannot be represented, especially results of floating-point calculations.
... for example, nans can represent infinity, result of division by zero, missing value, or the square root of a negative (which is imaginary, whereas a floating-point number is real).
... practically speaking, if i divide two variables in a javascript program, the result may be nan, which is predefined in javascript as "undefined".
...fortunately, since the result will be nan and i know my divisor may turn out to be 0, i can set up testing conditions that prevent any such computations in the first place or notify me of where they happen.

Introduction to CSS layout - Learn web development
these serve to move the affected element down and to the right — this might seem like the opposite of what you were expecting, but you need to think of it as the element being pushed on its left and top sides, which result in it moving right and down.

HTML basics - Learn web development
failing to add a closing tag is one of the standard beginner errors and can lead to strange results.
...if they overlap as shown above, then your web browser will try to make the best guess at what you were trying to say, which can lead to unexpected results.
...this includes things like keywords and a page description that you want to appear in search results, css to style our content, character set declarations and more.
... wrap the text in an <a> element, as shown below: <a>mozilla manifesto</a> give the <a> element an href attribute, as shown below: <a href="">mozilla manifesto</a> fill in the value of this attribute with the web address that you want the link to link to: <a href="https://www.mozilla.org/about/manifesto/">mozilla manifesto</a> you might get unexpected results if you omit the https:// or http:// part, called the protocol, at the beginning of the web address.

Images in HTML - Learn web development
our above code would give us the following result: note: elements like <img> and <video> are sometimes referred to as replaced elements.
...returning to our example, we could do this: <img src="images/dinosaur.jpg" alt="the head and torso of a dinosaur skeleton; it has a large head with long sharp teeth" width="400" height="341"> this doesn't result in much difference to the display, under normal circumstances.
... but if the image isn't being displayed, for example, the user has just navigated to the page, and the image hasn't yet loaded, you'll notice the browser is leaving a space for the image to appear in: this is a good thing to do, resulting in the page loading quicker and more smoothly.
...for example, to place a background image on every paragraph on a page, you could do this: p { background-image: url("images/dinosaur.jpg"); } the resulting embedded image, is arguably easier to position and control than html images.

Test your skills: Functions - Learn web development
note: in the examples below, if there is an error in your code it will be outputted into the results panel on the page, to help you try to figure out the answer (or into the browser's javascript console, in the case of the downloadable version).
...the three improvements we want you to make are: refactor the code that generates the random number into a separate function called random(), which takes as parameters two generic bounds that the random number should be between, and returns the result.
... update the choosename() function so that it makes use of the random number function, takes the array to choose from as a parameter (making it more flexible), and returns the result.
... print the returned result into the paragraph (para)'s textcontent.

Getting started with Svelte - Learn web development
it also compiles the markup and <script> section of every component and stores the result in public/build/bundle.js.
... using the svelte repl a repl (read–eval–print loop) is an interactive environment that allows you to enter commands and immediately see the results — many programming languages provide a repl.
... on the right side you have three tabs: the result tab shows your app output, and provides a console at the bottom.
... whenever you change any file on the repl, svelte will recompile the app and update the result tab.

Handling common HTML and CSS problems - Learn web development
let's go forth and look at how we can reduce cross browser errors that result from html/css.
... in your code, you can select sections of css you want to add prefixes to, open the command pallette (cmd/ctrl + shift + p), then type in autoprefixer and select the autoprefixer result that autocompletes.
...this results in some interesting browser prefix juggling if you want to try to use flexbox across all these browsers (see advanced cross-browser flexbox to get an idea).
...because of this, you need to use feature detection to detect whether visiting browsers support those layout features, and selectively apply different layouts depending on the result (we will cover feature detection in detail in a later article).

Deploying our app - Learn web development
however, doing this step manually isn't our final aim — what we want is for the build to happen automatically and the result of the dist directory to be deployed live on our website.
... and even better, whenever we make a change and push the change to our remote git repository (on github), this will trigger a notification to netlify which will then run our specified build task and then deploy the resulting dist directory to our published site.

...if searchactive is true, meaning that a search has been done, we want to disable the search as we hide the search options — we disable the buttons, make searchactive false, clear the entered search value, and run htmliframeelement.clearmatch(), which gets rid of any stored/highlighted search results from the browser.

HTMLIFrameElement.findNext()
the findnext() method of the htmliframeelement highlights the next or previous instance of a search result after a findall() search has been carried out.

Mail and RDF
answering queries: when rdf asks for information about a resource, datasources answer with the results of the query.
...this is basically what happens, behind the scenes: var target = rdf.getresource("mailbox://alecf@pop.myisp.com/inbox"); var property = rdf.getresource("http://home.netscape.com/nc-rdf#totalmessages"); var resultnode = datasource.gettarget(target, property, true); in the folder datasource's gettarget(), target would be queryinterfaced to a nsimsgfolder.
...finally, it would convert the result of this call to an rdf literal, and pass it back through the return parameter of gettarget().
... an example of how this might work inside the datasource: var msgcountarc = rdf.getresource("http://home.netscape.com/nc-rdf#totalmessages"); function gettarget(target, property, unused) { var folder = target.queryinterface(components.interfaces.nsimsgfolder); if (property == msgcountarc) { var msgcount = folder.gettotalmessages(false); var result = rdf.getliteral(msgcount.tostring()); return result; } } asynchronously notifying rdf when a mail object's data changes and the data is reflected in rdf by notifying all of the observers that rdf has registered with the datasource.

How whitespace is handled by HTML, CSS, and in the DOM - Web APIs
this article explores when difficulties can occur, and looks at what can be done to mitigate resulting problems.
...if there is formatting whitespace between adjacent inline elements, this will result in space in the layout, just like the spaces between words in text.
...for example, if you have a reference to a parent node and want to affect its first element child using node.firstchild, if there is a rogue whitespace node just after the opening parent tag you will not get the result you are expecting.
... as another example, if you have a certain subset of elements that you want to do something to based on whether they are empty (have no child nodes) or not, you could check whether each element is empty using something like node.haschildnodes(), but again, if any target elements contain text nodes, you could end up with false results.

SpeechRecognition.continuous - Web APIs
the continuous property of the speechrecognition interface controls whether continuous results are returned for each recognition, or only a single result.
... it defaults to single results (false.) syntax var mycontinuous = myspeechrecognition.continuous; myspeechrecognition.continuous = true; value a boolean representing the current speechrecognition's continuous status.
... true means continuous, and false means not continuous (single result each time.) examples this code is excerpted from our speech color changer example.
