import - JavaScript
import { reallyreallylongmoduleexportname as shortname, anotherlongmodulename as short } from '/modules/my-module.js'; import a module for its side effects only import an entire module for side effects only, without importing anything.
... import '/modules/my-module.js'; this works with dynamic imports as well: (async () => { if (somethingistrue) { // import module for side effects await import('/modules/my-module.js'); } })(); if your project uses packages that export esm, you can also import them for side effects only.
...(static import only supports static specifiers.) when the module being imported has side effects, and you do not want those side effects unless some condition is true.
... (it is recommended not to have any side effects in a module, but you sometimes cannot control this in your module dependencies.) use dynamic import only when necessary.

Performance fundamentals - Web Performance
rich applications use dynamic content with animation and transition effects.
...this works well because the browser is designed to optimize these effects and use the gpu to handle them smoothly with minimal impact on processor performance.
... another benefit is that you can define these effects in css along with the rest of your app's look-and-feel, using a standardized syntax.
... css animations give you very granular control over your effects using keyframes, and you can even watch events fired during the animation process in order to handle other tasks that need to be performed at set points in the animation process.

describe all side-effects on "out" parameters.

NSS 3.16.4 release notes

Cross-Origin Resource Sharing (CORS) - HTTP
additionally, for http request methods that can cause side-effects on server data (in particular, http methods other than get, or post with certain mime types), the specification mandates that browsers "preflight" the request, soliciting supported methods from the server with the http options request method, and then, upon "approval" from the server, sending the actual request.

Content-Security-Policy-Report-Only - HTTP
the http content-security-policy-report-only response header allows web developers to experiment with policies by monitoring (but not enforcing) their effects.

Pragma - HTTP
the pragma http/1.0 general header is an implementation-specific header that may have various effects along the request-response chain.

PATCH - HTTP
patch (like put) may have side-effects on other resources.

POST - HTTP
the difference between put and post is that put is idempotent: calling it once or several times successively has the same effect (that is no side effect), where successive identical post may have additional effects, like passing an order several times.

PUT - HTTP
the difference between put and post is that put is idempotent: calling it once or several times successively has the same effect (that is no side effect), whereas successive identical post requests may have additional effects, akin to placing an order several times.

HTTP request methods - HTTP
post the post method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

Control flow and error handling - JavaScript
in older javascript, variables introduced within a block are scoped to the containing function or script, and the effects of setting them persist beyond the block itself.

Default parameters - JavaScript
c = b; case 3: d = go(); case 4: e = this; case 5: f = arguments; case 6: g = this.value; default: } return [a, b, c, d, e, f, g]; } withdefaults.call({value: '=^_^='}); // [undefined, 5, 5, ":p", {value:"=^_^="}, arguments, "=^_^="] withoutdefaults.call({value: '=^_^='}); // [undefined, 5, 5, ":p", {value:"=^_^="}, arguments, "=^_^="] scope effects if default parameters are defined for one or more parameter, then a second scope (environment record) is created, specifically for the identifiers within the parameter list.

RegExp.$1-$9 - JavaScript
regexp.$1 : '0'; number; // "24" please note that any operation involving the usage of other regular expressions between a re.test(str) call and the regexp.$n property, might have side effects, so that accessing these special properties should be done instantly, otherwise the result might be unexpected.

Logical AND (&&) - JavaScript
short-circuit evaluation the logical and expression is evaluated left to right, it is tested for possible "short-circuit" evaluation using the following rule: (some falsy expression) && expr is short-circuit evaluated to the falsy expression; short circuit means that the expr part above is not evaluated, hence any side effects of doing so do not take effect (e.g., if expr is a function call, the calling never takes place).

Logical AND assignment (&&=) - JavaScript
syntax expr1 &&= expr2 description short-circuit evaluation the logical and operator is evaluated left to right, it is tested for possible short-circuit evaluation using the following rule: (some falsy expression) && expr is short-circuit evaluated to the falsy expression; short circuit means that the expr part above is not evaluated, hence any side effects of doing so do not take effect (e.g., if expr is a function call, the calling never takes place).

Logical OR (||) - JavaScript
short circuit means that the expr part above is not evaluated, hence any side effects of doing so do not take effect (e.g., if expr is a function call, the calling never takes place).

Logical OR assignment (||=) - JavaScript
examples setting default content if the "lyrics" element is empty, set the innerhtml to a default value: document.getelementbyid('lyrics').innerhtml ||= '<i>no lyrics.</i>' here the short-circuit is especially beneficial, since the element will not be updated unnecessarily and won't cause unwanted side-effects such as additional parsing or rendering work, or loss of focus, etc.

Logical nullish assignment (??=) - JavaScript
short circuit means that the expr part above is not evaluated, hence any side effects of doing so do not take effect (e.g., if expr is a function call, the calling never takes place).

this - JavaScript
it's not exactly dead because it gets executed, but it can be eliminated with no outside effects.) as a dom event handler when a function is used as an event handler, its this is set to the element on which the listener is placed (some browsers do not follow this convention for listeners added dynamically with methods other than addeventlistener()).

void operator - JavaScript
this can cause unintended side effects by returning the result of a function call that previously returned nothing.

block - JavaScript
variables introduced within a block are scoped to the containing function or script, and the effects of setting them persist beyond the block itself.

Digital audio concepts - Web media technologies

Animation performance and frame rate - Web Performance
there are a number of elements, and we've added a linear-gradient background and a box-shadow to each element, because they are both relatively expensive effects to paint.

Mobile first - Progressive web apps (PWAs)
therefore, as well as splitting content into different views, and simplifying the interface and content on each view of your application for mobile as much as possible, it is also a good idea to not include visual effects such as shadows, animations, and gradients.

The building blocks of responsive design - Progressive web apps (PWAs)
some ideas follow, which also help to keep the number of http requests down — another key factor in mobile app performance: you should try to use css3 features to programmatically generate graphical effects where possible, rather than relying on image files.

How to turn off form autocompletion - Web security
off": autocomplete="off" you can do this either for an entire form, or for specific input elements in a form: <form method="post" action="/form" autocomplete="off"> […] </form> <form method="post" action="/form"> […] <div> <label for="cc">credit card:</label> <input type="text" id="cc" name="cc" autocomplete="off"> </div> </form> setting autocomplete="off" on fields has two effects: it tells the browser not to save data inputted by the user for later autocompletion on similar forms, though heuristics for complying vary by browser.
