How do you replace all whitespaces in a string

To remove all whitespace from a string in JavaScript, call the replace() method on the string, passing a regular expression that matches any whitespace character, and an empty string as a replacement. For example, str. replace(/\s/g, '' ) returns a new string with all whitespace removed from str .

Approach:

  1. In the given string Str, replace all occurrences of Sub with empty spaces.
  2. Remove unwanted empty spaces in start and end of the string.
  3. Print the modified string.

In this simple approach, we are using the replace() function in JavaScript. This function uses the regular expression ('/ /g'). The 'g' flag used here assures that all occurrences of spaces are properly replaced with the “%20” encoding sequences throughout the entire string.

What is %20 in string : For example, spaces in a string are either encoded with %20 or replaced with the plus sign ( + ). If you use a pipe character ( | ) as a separator, be sure to encode the pipe as %7C . A comma in a string should be encoded as %2C .
