How to clone object in JavaScript?

You can directly copy a new object using assign  in javascript like below

var Cloned_new_object = Object.assign({}, OriginalObject);

// The "Cloned_new_object" variable now consists of all "Original_object" keys and values.
// Both variables are independent. Either one can be edited.

Or you can create own function like below

    function CopyObjectFunction(a) {
        // "use strict";
        // Un-comment the "use strict" directive statement if
        // this function is placed outside your own function.
        var result = {};
        var buff = [];
        var l;
        if (a.constructor === Object) { // check if the input is an Object type.
            buff = Object.keys(a); // get all keys of the input Object.
            l = buff.length; // the length of the keys (array now).
            if (l > 0) { // if the keys length greater than 0 (there's key found).
                buff.forEach(function (v) {
                    result[v] = a[v];
                });
            }
        }
        // the result.
        // if the input is an empty object, then the procedure above will be skipped.
        return result;
    }

and use it like below

var new_cloned_object = CopyObjectFunction(OriginalObject);

That's it, you are done.
