2d character movement javascript (help im bad)

So I just started using Unity and got Visual Studio code. I coded a robot using JavaScript so I know some stuff but game development is quite different.

I already have the character colliders and everything and that works. So can someone point me in the right direction to make my 2d character move? I use JavaScript as stated above.

JavaScript is depreciated C# is the standard now. There are tons of video tutorials out there to do exactly what you want take a look on youtube.
