How to Remove Non-ASCII Characters in JavaScript

To remove non-printable ASCII characters in JavaScript, you can follow these steps:

  1. Open the Terminal/SSH and type node to start practicing coding.
  2. Use the String.prototype.replace() method with a regular expression to remove non-printable ASCII characters.
  3. The regular expression /[^\x20-\x7E]/g matches any character that is not in the printable ASCII range (decimal values 32 to 126).
  4. The g flag is used to perform a global match (i.e., replace all occurrences of non-ASCII characters in the string).
  5. Here's an example of how to use the removeNonASCII function:
const removeNonASCII = (str) => str.replace(/[^\x20-\x7E]/g, "");

removeNonASCII("äÄçÇéÉêlorem-ipsumöÖÐþúÚ"); // 'lorem-ipsum'

This will return the string with all non-ASCII characters removed.
