How to replace all spaces in a string

Pure Javascript, without regular expression:

var result = replaceSpacesText.split(" ").join("");

takes care of multiple white spaces and replaces it for a single character

myString.replace(/\s+/g, "-")

var result = replaceSpace.replace(/ /g, ";");

Here, / /g is a regex (regular expression). The flag g means global. It causes all matches to be replaced.
