Trim a string in JavaScript using trim() method

In this tutorial, we are going to learn about how to trim a string in JavaScript.

Using the trim() method

JavaScript has a built-in trim() method by using that we can remove the whitespaces from the both ends of a string.

Here is an example that trims the following string:

const name = "   olive   ";

console.log(name.trim()); //  "olive"

Similarly, we can also use the split() and join() methods to trim the string.

const name = "   olive   ";

const trimmedString = name.split(" ").join(""));

console.log(trimmedString); // "olive"
