API

clone([mixed], [[options]])

Clones an object, recursively.

import clone from 'lutils-clone'

const test = new class Test {}

const obj = {
    a  : { b: 2 },
    fn : function() {}
    test,
}

const newObj = clone(obj)

newObj.a.b = 5

obj.a.b               // 2
newObj.a === obj.a    // false
newObj.test === test  // false
newObj.test.__proto__ === test.__proto__ // true
newObj.fn === obj.fn  // true

Advanced usage

Options

{
    // Decremented with each recursion for each nested object, halting the clone at 0
    // A halted clone will preserve references to any remaining values
    depth: 8,

    // Determines whether recursing will occur. When this type matches, it will be iterated over.
    types: { object: true, array: true }
    types: [ "object", "array" ] // Can also be an array of type strings
}
