JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Working with Strings and Finding Help

Troubles getting the console to work.

I am using Microsoft Windows 10 and Edge as Browser. As soon as I am pressing the F12 Button something that could be the JavaScript Console appears. But whenever I run my script I get a bunch of really un-understandable messages like: SCRIPT5007: Unable to get property 'clientWidth' of undefined or null reference terminal.js (108,7)

My script looks like this: var passphrase = "Open Sesame"; console.log(passphrase.length); console.log(passphrase.toLowerCase()); console.log(passphrase); console.log(passphrase.toUpperCase());

So far, the code was not tooo long or complex and I could fix all bugs without debugging - but I need the debugger - I want to learn to use it :-(

PLEASE HELP!!! :-(

Try using Google Chrome.

It is not (yet) installed on my computer. So far I am using either Mozilla Firefox or Edge. I already tried Mozilla Firefox - and the Java Script Console did not work either. So for sure I can Install a third Browser on my Computer - but how likely is it that I get/don´t get problems (compatibility ...)

Google Chrome is one of the best browsers for programming HTML, CSS, and JavaScript because it supports the most useful things.

I never heard of Edge before, but i do know that:

  • :x: IE isn't good for modern JS/CSS/HTML programming because it doesn't support enough modern features
  • Firefox is okay for front-end development
  • Safari is ok
  • :white_check_mark: Google Chrome is the best choice for HTML/CSS/JS development! :point_left:
