2. Program to Remove All Whitespace From a Text Using Regular Expression.

In this program, we first define a string text that contains some whitespace. Then, we use the replace() method to replace all whitespace characters with an empty string. The regular expression /\s/g matches all whitespace characters in the string, and the g flag ensures that all occurrences are replaced.

The resulting string with no whitespace is stored in the newText variable, which we then log to the console.

You can replace the text variable with any string that you want to remove whitespace from.

const text = "JavaScript is the world's most popular programming language.";
const newText = text.replace(/\s/g, "");

console.log(newText);
