Split JavaScript array in chunks using Lodash

Question

I need to split a JavaScript array into n sized chunks.

E.g.: Given this array

["a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12", "a13"]

and a n equals to 4, the output should be this:

[ ["a1", "a2", "a3", "a4"],
  ["a5", "a6", "a7", "a8"],
  ["a9", "a10", "a11", "a12"],
  ["a13"]
]

I aware of pure JavaScript solutions for this problem, but since I am already using Lodash I am wondering if Lodash provides a better solution for this.

Edit:

I created a jsPerf test to check how much slower the underscore solution is.

Take a look at lodash' chunk: https://lodash.com/docs#chunk

const data = ["a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12", "a13"];
const chunks = _.chunk(data, 3);
console.log(chunks);
// [
//  ["a1", "a2", "a3"],
//  ["a4", "a5", "a6"],
//  ["a7", "a8", "a9"],
//  ["a10", "a11", "a12"],
//  ["a13"]
// ]
