Sometimes, we want to compare JavaScript strings and get end difference.

In this article, we’ll look at how to compare JavaScript strings and get end difference.

How to compare JavaScript strings and get end difference?

To compare JavaScript strings and get end difference, we can use the JavaScript string’s split and join methods.

For instance, we write:

const a = "The quick brown fox"
const b = "The quick brown fox jumps over the lazy dog."

const diff = (diffMe, diffBy) => diffMe.split(diffBy).join('')

const c = diff(b, a)
console.log(c)

We create the diff function by calling split with diffBy and then calling join to join back the substring array returned by split.

Then we call diff with b and a to split b with a as the separator.

As a result, we get c, which is ' jumps over the lazy dog.'.

Conclusion

To compare JavaScript strings and get end difference, we can use the JavaScript string’s split and join methods.
