The most accessible way is to take video courses on platforms like skillshare or udemy. There you will find cheap but very valuable courses.
I have just completed a 52 hours javascript video course and I have learned a lot. You can find a video review of the course I have followed here:

This is not the first course I did on udemy. I am also registered at skillshare where you pay just a monthy fee of about 10 bucks and you get access to thousands of courses. I think this is a great way to learn and accessible to everybody.
