title: Use the JavaScript Console
|
||
|
---
|
||
|
Both Chrome and Firefox have excellent JavaScript consoles, also known as DevTools, for debugging your JavaScript.
|
||
|
|
||
|
You can find Developer tools in your Chrome's menu or Web Console in FireFox's menu. If you're using a different browser, or a mobile phone, we strongly recommend switching to desktop Firefox or Chrome.
|
||
|
|
||
|
You can also use <a href='https://repl.it/' target='_blank' rel='nofollow'>https://repl.it/</a> to run code online.

|
||
|
This is how you print to the console:
|
||
|
|
||
|
console.log('Hello world!')
|
||
|
|
||
|
Also You can print an error log in the console with this code:
|
||
|
|
||
|
console.error('I am an error!')
