... // replaces olds with news in the string fulls function replacestring(olds, news, fulls) { for (let i = 0; i < fulls.length; ++i) { if (fulls.substring(i, i + olds.length) == olds) { fulls = fulls.substring(0, i) + news + fulls.substring(i + olds.length, fulls.length) } } return fulls } replacestring('world', 'web', 'brave new world') note that this can result in an infinite loop if olds is itself a substring of news — for example, if you attempted to replace 'world' with 'otherworld' here.
... a better method for replacing strings is as follows: function replacestring(olds, news, fulls) { return fulls.split(olds).join(news) } the code above serves as an example for substring operations.

Reference Manual
like nsisupports* (or even void*), people generally use nscomptr<nsisupports> to mean "any xpcom interface." it would be annoying if nscomptr forced you to queryinterface to the xpcom-correct nsisupports within an object in places where you don't care to know the exact type.
...time [[more time-performance measurements are needed.]] in places where two or more subroutines calls are required, i.e., of addref, release, and queryinterface, some nscomptr routines are factored, and hence, require additional time corresponding to invoking a subroutine.

Call Tree - Firefox Developer Tools
by analyzing its results, you can find bottlenecks in your code - places where the browser is spending a disproportionately large amount of time.
... these bottlenecks are the places where any optimizations you can make will have the biggest impact.

Animation.persist() - Web APIs
llowing code: const divelem = document.queryselector('div'); document.body.addeventlistener('mousemove', evt => { let anim = divelem.animate( { transform: `translate(${ evt.clientx}px, ${evt.clienty}px)` }, { duration: 500, fill: 'forwards' } ); anim.commitstyles(); //anim.persist() anim.onremove = function() { console.log('animation removed'); } console.log(anim.replacestate); }); here we have a <div> element, and an event listener that fires the event handler code whenever the mouse moves.
... you can see the replacestate of the animation being logged at the end of the handler.

Animation - Web APIs
animation.replacestate returns the replace state of the animation.
... animation.replacestate to return the replace state of the animation.

Element.innerHTML - Web APIs
setting the value of innerhtml removes all of the element's descendants and replaces them with nodes constructed by parsing the html given in the string htmlstring.
... for example, you can erase the entire contents of a document by clearing the contents of the document's body attribute: document.body.innerhtml = ""; this example fetches the document's current html markup and replaces the "<" characters with the html entity "&lt;", thereby essentially converting the html into raw text.

FetchEvent - Web APIs
fetchevent.replacesclientid read only the id of the client that is being replaced during a page navigation.
... fetchevent.resultingclientid read only the id of the client that replaces the previous client during a page navigation.

FileSystemEntrySync - Web APIs
moving a file over an existing file replaces that existing file.

NamedNodeMap - Web APIs
namednodemap.setnameditem() replaces, or adds, the attr identified in the map by the given name.
... namednodemap.setnameditemns() replaces, or adds, the attr identified in the map by the given namespace and related local name.

Using bounded reference spaces - Web APIs
therefore, the bounded reference space's origin always places the y=0 plane at floor level.
...the new reference space replaces the original one.

Inputs and input sources - Web APIs
this code presumes the existence of additional functions findtargetposition(), which follows the target ray until it collides with something, then returns the coordinates at which the collision occurred, and putobject(), which places the object held in the specified hand at the given position, removing it from the hand.
... the applyexternalinputs() method takes the avatar object replaces its referencespace property with a new reference space that incorporates the updated deltas.

Movement, orientation, and motion: A WebXR example - Web APIs

Handling content breaks in multicol - CSS: Cascading Style Sheets
a column box can contain other markup and there are many places where a break would not be ideal.
... there are various places we might want to control our breaks: breaks inside boxes, for example inside a figure element.

content - CSS: Cascading Style Sheets
the content css property replaces an element with a generated value.
...loper network</a></li> </ul> css a { text-decoration: none; border-bottom: 3px dotted navy; } a::after { content: " (" attr(id) ")"; } #moz::before { content: url("https://mozorg.cdn.mozilla.net/media/img/favicon.ico"); } #mdn::before { content: url("https://mdn.mozillademos.org/files/7691/mdn-favicon16.png"); } li { margin: 1em; } result element replacement this example replaces an element's content with an image.

examples encoding encoding replaces each instance of certain characters by one, two, three, or four escape sequences representing the utf-8 encoding of the character.
...for example: encodeuri('\ud800\udfff'); // "%f0%90%8f%bf" decoding decoding replaces each escape sequence in the encoded uri component with the character that it represents.

RegExp.prototype[@@replace]() - JavaScript
the [@@replace]() method replaces some or all matches of a this pattern in a string by a replacement, and returns the result of the replacement as a new string.
... newsubstr (replacement) the string that replaces the substring.

String.prototype.replace() - JavaScript
newsubstr (replacement) the string that replaces the substring specified by the specified regexp or substr parameter.
... replacing a fahrenheit degree with its celsius equivalent the following example replaces a fahrenheit degree with its equivalent celsius degree.

void operator - JavaScript
syntax void expression description this operator allows evaluating expressions that produce a value into places where an expression that evaluates to undefined is desired.
... javascript uris when a browser follows a javascript: uri, it evaluates the code in the uri and then replaces the contents of the page with the returned value, unless the returned value is undefined.

Content Scripts - Archive of obsolete content
the content script simply replaces the content of the page: // main.js var tabs = require("sdk/tabs"); var contentscriptstring = 'document.body.innerhtml = "<h1>this page has been eaten</h1>";' tabs.activetab.attach({ contentscript: contentscriptstring }); the following high-level sdk modules can use content scripts to modify web pages: page-mod: enables you to attach content scripts to web pages that match a specific url ...

Module structure of the SDK - Archive of obsolete content
for example, this add-on places external modules in a "dependencies" directory: my-addon lib main.js dependencies geolocation.js it can then load them in the same way it would load a local module.

An Overview of XPCOM
in the haste of early mozilla development, components were created where they were inappropriate, but there's been an ongoing effort to remove xpcom from places like this.

Finishing the Component
in this context, uris are the strings used refer to places or things on the web.

Packaging WebLock
once triggered (see the weblock trigger script), the installation script: downloads the weblock component and places it in the components directory copies the weblock subdirectory in the mozilla chrome application subdirectory registers both the component and the ui the xpinstall api provides such essential methods[essential-methods] as initinstall, registerchrome, addfile, and others.

Starting WebLock
in other places, where allocated buffers cross interface boundaries, you must ensure that the correct allocator is used - namely nsmemory - so that the allocators can match the allocation with the deallocation.

Using XPCOM Utilities to Make Things Easier
but there are only a few places in that code that are unique to the weblock component, and it was a lot of typing.
