make-tree v2.0.0

Turns an array of strings [ 'grandparent', 'parent', 'child' ] into a tree of objects:

{
	grandparent: {
		parent: {
			child: {

			}
		}
	}
}

With one simple function call:

const makeTree = require('make-tree')

const child = makeTree([ 'grandparent', 'parent', 'child' ], {})

makeTree(ary, obj)

• ary: an array of strings representing keys. If any of those keys does not exist in the hierarchy, they will be created as an empty object.
• obj: the object to be modified by the creation of new descendants

Returns the final object in the hierarchy represented in the array.

const inputObject = {
	parent: {
		child: {
			baby: 'goo!'
		}
	}
}

const child = makeTree([ 'parent', 'child' ], {parent: {child: {baby: 'goo!'}}})

console.log(child) // => { baby: 'goo!' }
