Sometimes, we want to split a string only the at the first n occurrences of a delimiter.

In this article, we’ll look at how to split a string only the at the first n occurrences of a delimiter.

Split a String Only the at the First n Occurrences of a Delimiter

To split a string only the at the first n occurrences of a delimiter, we can use the split method with the JavaScript array’s splice and join methods.

For instance, we write:

const string = 'Split this, but not this'
const arr = string.split(' ')
const result = arr.splice(0, 2)

result.push(arr.join(' '));
console.log(result)

We call split on the whole string.

Then we call splice to with 0 and 2 to get the first 2 items from the arr array and assign it to result.

The items returned by splice are removed from arr.

Next, we call arr.join with the remaining substrings in the arr array with a space to join them together.

Finally, we call result.push on that string to add that string to result.

Therefore, result is ['Split', 'this,', 'but not this'] according to the console log.

Conclusion

To split a string only the at the first n occurrences of a delimiter, we can use the split method with the JavaScript array’s splice and join methods.
