How to Remove Spaces in Javascript?

Assuming you want to remove all spaces in a string, you can use the replace() method. This method takes two arguments: the first is the regular expression you want to match, and the second is the string you want to replace it with. In this case, we want to match any space character (which is represented by \s), and replace it with an empty string.

var str = ‘This is a test string’;
str = str.replace(/\s/g,”);
console.log(str); // Thisisateststring

If you only want to remove leading or trailing spaces, you can use the trim() method instead. This method removes any whitespace characters from the beginning and end of a string.

var str = ‘ This is a test string ‘;
str = str.trim();
console.log(str); // This is a test string
