Replace all special characters in JavaScript | Example code

  • by

Use replace method with a regular expression to Replace all special characters in JavaScript.

stringToReplace.replace(/[^\w\s]/gi, '')

The caret (^) character is the negation of the set [...], gi say global and case-insensitive (the latter is a bit redundant but I wanted to mention it) and the safelist in this example is digits, word characters, underscores (\w) and whitespace (\s).
