I am wondering where is a good place online to learn JavaScript.
Develop games in your browser. Powerful, performant & highly capable.
w3schools.
start with it, go through whole html5 first, then javascript (and css eventually).
after that i'd recommend a few books - wrox webgl, html5 and javascript. (if you really want to devote to this job)
for me i watch YouTube and google search
and run over the software manual that i am going to use
i never went to any school nor college i teach myself therefore you can too
and the Guy that create this site i tip my hat off to him
https://www.thenewboston.com/
Or you can do http://www.codecademy.com that is an interactive way to learn. It covers many languages.
