Sometimes, we want to partition an array in JavaScript.

In this article, we’ll look at how to partition an array in JavaScript.

How to partition an array in JavaScript?

To partition an array in JavaScript, we can use the Lodash chunk function.

For instance, we write:

const arrayAll = [1, 2, 3, 4, 5, 6, 7, 8, 9]
const chunked = _.chunk(arrayAll, 3)
console.log(chunked)

to call chunk with arrayAll and 3 to return an array with entries in arrayAll divided into chunks of 3.

As a result, chunked is:

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Conclusion

To partition an array in JavaScript, we can use the Lodash chunk function.
