set-prop

Non-destructively set a nested property, given its path

Installation

$ npm install @micro-js/set-prop

var setProp = require('@micro-js/set-prop')
var obj = {a: {b: 1}}
var newObj = setProp('a.b', obj, 2)

obj.a.b === 1
newObj.a.b === 2
obj !== newObj

path - The path (specified as array or dotted string) of the property you wish to set
obj - The root object you want to set within
value - The value you want to assign to path within obj

Returns: A new root obj that has path changed to value, and all of the sub-objects in its tree cloned as well.
