clone vs deep clone

clone.js

function clone(value) {
    var result
    if (Array.isArray(value)) {
        result = []
        value.forEach(function (item) {
            result[result.length] = item
        })
    } else if (typeof value === 'object') {
        result = {}
        Object.keys(value).forEach(function (key) {
            result[key] = value[key]
        })
    } else {
        result = value
    }

    return result
}

module.exports = clone

cloneDeep.js

function cloneDeep(value) {
    var result
    if (Array.isArray(value)) {
        result = []
        value.forEach(function (item) {
            result[result.length] = cloneDeep(item)
        })
    } else if (typeof value === 'object') {
        result = {}
        Object.keys(value).forEach(function (key) {
            result[key] = cloneDeep(value[key])
        })
    } else {
        result = value
    }

    return result
}

module.exports = cloneDeep

test.js

let cloneDeep = require('./cloneDeep')
let clone = require('./clone')

let foo = {
    a: {
        a: 1,
        b: {
            c: [1,2]
        }
    }
}

let bar = cloneDeep(foo)
let eoo = clone(foo)

const dir = (arg) => console.dir(arg, {depth: Infinity})

dir(bar)
dir(foo)
console.log(bar != foo)
console.log(bar.a.b != foo.a.b)
console.log(bar.a.b.c != foo.a.b.c)

console.log(eoo != foo)
console.log(eoo.a.b == foo.a.b)
console.log(eoo.a.b.c == foo.a.b.c)
