String Replacement Calculator Calculator Usage Guide

Learn how to use the String Replacement Calculator calculator and its working principles

How to Use

  1. Enter the original string in the "Original String" field.
  2. Enter the substring you want to search for in the "Search String" field.
  3. Enter the substring you want to replace the search string with in the "Replacement String" field.
  4. Click the "Calculate" button to perform the string replacement.
  5. The result will be displayed in the "Result" section.

Working Principle

The calculator uses the JavaScript String.prototype.replace() method to replace all occurrences of the search string with the replacement string in the original string. The global flag ('g') in the regular expression ensures that all instances of the search string are replaced, not just the first one.

Example

If you enter "Hello World" in the original string, "World" in the search string, and "Earth" in the replacement string, the result will be "Hello Earth".
