yield vs Iterator.prototype.every()
yield and Iterator.prototype.every() are both JavaScript Iterator APIs, and choosing between them is a common point of confusion. This page compares their syntax, parameters, return values, and typical use cases so you can pick the right one. yield: Pauses a generator. Its syntax is yield expr. Iterator.prototype.every(): Tests if all values pass a test. Its syntax is iterator.every(callbackFn). Example of yield: function* gen() { yield 1 }. Example of Iterator.prototype.every(): Iterator.from([1,2,3]).every(x => x > 0) // true. Read the full references for yield and Iterator.prototype.every() to see edge cases, time complexity, browser support, and the mistakes developers most often make with each. Other Iterator APIs worth comparing: Iterator.prototype.find(), Iterator.prototype.some(), Iterator.prototype.forEach(), Iterator.prototype.reduce(), Iterator.prototype.toArray(). Both belong to the Iterator category in the JS Reference documentation, which covers 7 entries in total. Try both in the JavaScript playground to see the behavioral difference live.
