To remove whitespace from a string in JavaScript, you can use the replace () function with a regular expression. Here's an example of how to do this:



let myString = "   Hello, world!   ";
let trimmedString = myString.replace(/\s+/g, '');
console.log(trimmedString); // Output: "Hello,world!"

In the example above, the replace () function is called on the myString variable with a regular expression that matches one or more whitespace characters (\s+). The second argument to replace () is an empty string, which effectively removes all whitespace characters from the original string.

You can customize this code to remove whitespace in different ways, such as only removing leading or trailing whitespace. Additionally, you can modify the regular expression to remove only specific types of whitespace characters.
