use-strict

Besides use strict , which other use directives are there? GitaarLAB Some more examples that can be in the “directive prologue” (a section potentially usable by JavaScript engines): 'use strict'; 'use asm'; Mozilla's asm.js is a subset of the language, geared towards crunching numbers. 'use stricter'; Google's SoundScript. For fast OOP Has also some modes like: 'use stricter+types'; http://www.2ality.com/2015/02/soundscript.html 'use babel'; Used in Atom.io . (Was previously: 'use 6to5'; ) A tweet by Jeremy Ashkenas suggests some further use of + and - prefixes in the same 'use ...'; string (

JSLint gives me the "strict violation" error, although I use the "this" context inside a function which hides it from the global scope. function test() { "use strict"; this.a = "b"; } For the record, I use the built-in JSLint parser in Webstorm. This is because JSLint doesn't recognize your function as a constructor. By convention, you must use uppercase letters. function Test() { "use strict"; this.a = "b"; } 来源： https://stackoverflow.com/questions/17770048/why-does-jslint-give-strict-violation-error-on-this-function

There exist static analysis tools for Python , but compile time checks tend to be diametrically opposed to the run-time binding philosophy that Python embraces. It's possible to wrap the standard Python interpreter with a static analysis tool to enforce some " use strict "-like constraints, but we don't see any widespread adoption of such a thing. Is there something about Python that makes "use strict" behavior unnecessary or especially undesirable? Alternatively, is the "use strict" behavior unnecessary in Perl, despite its widespread adoption? Note: By "necessary" I mean "practically

I recently started using JSHint and it is requiring me to use the function form of "use strict". Since then, AngularJS throws an error: "Error: Argument 'webAddressController' is not a function, got undefined" When I remove the function form of "use strict" the controller loads fine. Controller: (function () { "use strict"; function webAddressController($scope, $rootScope, web_address_service) { // Do things } }()); Does anyone have any insight on what's going on here? Ben Lesh First off, I want to state the pkozlowski really knows his stuff at Angular, but this actually isn't as much of an

I'm new to javascript and am trying to validate through JSLint. Where should I put "use strict" to use it globally and validate? This gives me error "Unexpected expression 'use strict' in statement position.": "use strict"; console.log('doing js in head-section'); function helloWorld() { console.log('called function helloWorld()'); alert('Hello World from a JS function showing an alert!'); } function helloMyNumber() { console.log('called function helloMyNumber()'); var max = 42; var yourLuckyNumber = prompt('Enter your lucky number (between 1 and '+ max +')'); var myLuckyNumber = Math.floor

Suppose I have the following script, called include_strict.js . After it executes I should have window.global1 defined: "use strict"; var globalVar = {}; alert(typeof window.globalVar); But if I include it from a block of javascript with $.getScript("include_strict.js"); The alert says undefined . Why? What is going on here? FYI, that's not what happens if I include the file using a script tag: <script type="text/javascript" src="include_strict.js"></script> Here, I see the expected alert, object . And if I remove "use strict"; , then both jQuery.getScript() and <script>; have the same effect

"use strict"; seems awesome, and we'd really like to use it at our shop. However, we just want it so that we (the developers) can find strictness-issues; we very much DO NOT want to make our site break for our actual customers when it was working fine before. Now, we could just use some server-side logic to achieve this: {% if debug %}<script>"use strict";</script>{% endif %} ... except that "use strict" operates on a file-by-file basis, so that won't actually work (well, unless we start server-side processing all of our JS files). So, my question is: do all the things "use strict" checks for
