map() can be used to iterate through objects in an array and, in a similar fashion to traditional arrays, modify the content of each individual object and return a new array. This modification is done based on what is returned in the callback function.
JavaScript | Array map() Method The map() method in JavaScript creates an array by calling a specific function on each element present in the parent array. It is a non-mutating method. Generally map() method is used to iterate over an array and calling function on every element of array.
Array.prototype.map() The map() method creates a new array populated with the results of calling a provided function on every element in the calling array.
IE11 has ES5, not ES6
var vector = labelsPrint.map(function (el) { return el.id; });
