    I don’t think I’ve ever use regex in javascript. Thanks for the reminder that you can!

    Thanks for this nice tip of using regex

  3. The same thing can be achieved with:

    var someString = “Hello 123 World!”;
    newString = someString.replace(/\d+/g, ”);

Posting Code

  • Use Markdown, and it will escape the code for you, like `<div class="cool">`.
  • Use triple-backticks for blocks of code.
      <h1>multi-line block of code</h1>
      <span>be cool yo.</span>
  • Otherwise, escape your code, like <code>&lt;div class="cool"&gt;</code>. Markdown is just easier though.
