How to Compress Multiple Spaces into a Single Space with Regex?

Regex Solution for Compressing Multiple Spaces into a Single Space

Replacing multiple spaces with a single space is a common task in text processing. Here's a jQuery or JavaScript solution using a regular expression to achieve this goal:

string = string.replace(/\s\s+/g, ' ');

This regex uses a global search (g) to identify all occurrences of two or more consecutive spaces (ss ) and replaces them with a single space.

If you want to specify only spaces and exclude other whitespace characters (e.g., tabs, newlines), use this modified regex:

string = string.replace(/  +/g, ' ');

Here's an example of how the modified regex works:

const input = "The dog      has a long   tail, and it     is RED!";
const output = input.replace(/  +/g, ' ');
console.log(output); // Outputs: "The dog has a long tail, and it is RED!"

By applying this regex, you can effectively compress any consecutive spaces in a string into just one space, making the text more readable and consistent.
