fmerge

fmerge

fmerge is a simple tool for merging objects. It is perfect for handling options objects.

It takes any number of parameters. It even merges recursively. Arrays will just be replaced, though.

It does require a browser that supports ES5 methods though, so for IE8 or earlier, take a look at https://github.com/olivernn/augment.js.

Example of use

var merge = require('fmerge')

console.log(merge(
  { a: 1, b: { c: 3, d: 4 }, [ 'entry', { e: 5 } ] }
, { a: 2, b: { a: 1, c: 2 }, [ 'another entry', { a: 1 } ] }
))
// { a: 2, b: { a: 1, c: 2, d: 4 }, [ 'another entry', { a: 1 } ] }
