I don't even know what's more to say here.
Comes from the video tutorial on how to build a life-changing app with just JavaScript:
• An Absolute Beginner Can Build This! ...
And here is the unknown poem written by Leo Tolstoy on how to NOT use the browser console:
In the world of web development,
There's a tool that many employ,
A powerful console at their fingertips,
A place to debug and enjoy.
But heed my words, dear reader,
Lest you fall into temptation's snare,
For the console is a double-edged sword,
That can cause your website to tear.
Do not use the console for evil,
To change things on the fly,
For this will lead to chaos,
And make your code go awry.
Instead, use it for good,
To find and fix what's wrong,
To log important data,
And make your website strong.
So remember Tolstoy's words,
And use the console with care,
For it can be a friend or foe,
And your website's fate it can ensnare.
