The JavaScriptfor/ofstatement loops through the values of an iterable objects. for/oflets you loop over data structures that are iterable such as Arrays, Strings, Maps, NodeLists, and more. Thefor/ofloop has the following syntax: for(variableofiterable) { ...
EnhancedForLoop: a “for-in” or “for-of” loop; use EnhancedForLoop.getIterator() to access the loop iterator (which may be a expression or variable declaration), and EnhancedForLoop.getIterationDomain() to access the expression being iterated over. ForInStmt, ForOfStmt: a “for-in”...
You can minify more than one JavaScript file at a time by using an object for the first argument where the keys are file names and the values are source code: var code = { "file1.js": "function add(first, second) { return first + second; }", "file2.js": "console.log(add(1 ...
The keys before, after, beforeEach, and afterEach are special-cased, object values are suites, and function values are test-cases: module.exports = { before: function() { // ... }, Array: { '#indexOf()': { 'should return -1 when not present': function() { [1, 2, 3].index...
Jessie has no for/in statement, and so does not inherit the non-determinism regarding property modification during for/in enumeration. Everything useful about for/in is still available byObject.keys,Object.valuesandObject.entries, (or in TinySES through reflection) but without this non-determinism...
When there isn't an active edit workflow, the FeatureFormViewModel and SketchViewModel properties are null. When an editing workflow begins, these properties will have values, but any changes or event handlers made to them are only applicable for the duration of that workflow. The Mesh...

The implementation of repeat uses the _.map function to loop over an array of the numbers 0 to times - 1, plopping VALUE into an array 4 times. You’ll notice that the anonymous function closes over the VALUE variable, but that’s not very important (nor terribly interesting, in this ...
5.3 Use object destructuring for multiple return values, not array destructuring. Why? You can add new properties over time or change the order of things without breaking call sites. // bad function processInput(input) { // then a miracle occurs return [left, right, top, bottom]; } // ...
