I went through many free JavaScript coding modules like Code Academy, FreeCodeCamp.org, and CodeSchool.com. These are great for testing the waters, but eventually you have to pay to go deeper into the lessons. Instead, go to Hack Reactor and sign up for their free prep program which provides structured learning (with videos, exercises, and reading) so that you can eventually apply for their intensive 10 week bootcamp. https://www.hackreactor.com/prep-programs
