Want to learn JavaScript ?

Here's a Detailed Roadmap for you

1. Start with http://freecodecamp.org 's - JavaScript Algorithms and Data Structures Certification and finish the "Basic JavaScript" module.

You'll get a basic understanding of JavaScript and Programming in general.

2. Move to http://JavaScript.info  and complete the following parts:
- An Introduction
- JavaScript Fundamentals
You'll start to understand Basic JavaScript concepts and their details.

3. Complete "Objects: the basics" section in http://JavaScript.info 

By this point you'll have a decent understanding of JavaScript Objects

4. Time to return to freeCodeCamp. Finish the following sections:
1. Debugging
2. Basic Data Structure

5. Complete "Data types" Section in http://JavaScript.info 

Congratulations!

3. Functional Programming

7. Finish Part 1 of http://JavaScript.info 

8. Finish freeCodeCamp's JavaScript Algorithms and Data Structures Certification

9. Now you'll have to learn something called DOM. For that you'll need a basic understanding of HTML and CSS.

For learning DOM, I would recommend the following two resources:
1. Part 2 of http://JavaScript.info
