fast-path-set

A fast drop-in replacement for lodash.set.

Install

$ npm i fast-path-set --save

Usage

const set = require('fast-path-set')
const obj = {}
set(obj, 'a.b.c', 1)
console.log(obj.a.b.c)

Check test.js for more detailed usage examples. There is one key difference to lodash.set, which is the fact fast-path-set will prioritise safety and abort attempts to overwrite non-object values. It also correctly prevents prototype pollution attacks.
