1 2 {{alias}}( src[, mapFcn[, thisArg]] ) 3 Returns an iterator which iterates over the elements of an array-like 4 object. 5 6 When invoked, an input function is provided three arguments: 7 8 - value: iterated value 9 - index: iterated value index 10 - src: source array-like object 11 12 If an environment supports Symbol.iterator, the returned iterator is 13 iterable. 14 15 If an environment supports Symbol.iterator, the function explicitly does not 16 not invoke an array's `@@iterator` method, regardless of whether this method 17 is defined. To convert an array to an implementation defined iterator, 18 invoke this method directly. 19 20 Parameters 21 ---------- 22 src: ArrayLikeObject 23 Array-like object from which to create the iterator. 24 25 mapFcn: Function (optional) 26 Function to invoke for each iterated value. 27 28 thisArg: any (optional) 29 Execution context. 30 31 Returns 32 ------- 33 iterator: Object 34 Iterator. 35 36 iterator.next(): Function 37 Returns an iterator protocol-compliant object containing the next 38 iterated value (if one exists) and a boolean flag indicating whether the 39 iterator is finished. 40 41 iterator.return( [value] ): Function 42 Finishes an iterator and returns a provided value. 43 44 Examples 45 -------- 46 > var it = {{alias}}( [ 1, 2, 3, 4 ] ); 47 > var v = it.next().value 48 1 49 > v = it.next().value 50 2 51 52 See Also 53 -------- 54
