How to compare arrays in JavaScript?

Spread the love

To compare arrays in JavaScript, we use the JSON.stringify method.

For instance, we write

const isSame = JSON.stringify(a1) === JSON.stringify(a2);

to convert arrays a1 and a2 to JSON strings with JSON.stringify.

And then we compare the strings with ===.
