Fast Array Clone Library

This library can 200X times faster than lodash (benchmark) make deep copies of an array or objects with similar structure in JavaScript

EXAMPLE

// array of SAME STRUCTURED object
var sourceArray = [{ f1 : ..., f2: ... }, ...];

You can use built-in array clone function:

var clonedArray = FastClone.cloneArray(sourceArray);

or object clone constructor factory:

// creating deep clone constructor function
var Clone = FastClone.factory(sourceArray[0]);
var clonedArray = sourceArray.map(function(item) {
    // you can add here custom logic
    return new Clone(item);
});
