Sometimes, we want to split array into two arrays with JavaScript.
In this article, we’ll look at how to split array into two arrays with JavaScript.
How to split array into two arrays with JavaScript?
To split array into two arrays with JavaScript, we can use the array slice method.
For instance, we write
const arr = ["a", "b", "c", "d", "e", "f"];
const indexToSplit = arr.indexOf("c");
const first = arr.slice(0, indexToSplit);
const second = arr.slice(indexToSplit + 1);
to call indexOf to get the index of 'c'.
Then we call slice with 0 and indexToSplit to return an array with arr entries from index 0 to indexToSplit - 1.
Next we call slice again with indexToSplit + 1 to return an array from index indexToSplit + 1 to the end of the arr array.
Conclusion
To split array into two arrays with JavaScript, we can use the array slice method.
