Week 07 - Day 1 | Just Enough JavaScript - Part 1

Schedule

Study Plan

This Module is about learning “Just enough JavaScript” in order to understand, trace and debug the execution process of JavaScript programs and learn how to read and comprehend every single line of code that you see. That’s probably the most important task, anyone learning a new language (even natural languages), must go through in order to become familiar with this new fascinating territory.

In order to follow the material, you will need to install and use the study-lenses tool. Here are the instructions:

Setting up Study Lenses (v2) on your System

  1. Clone the study-lenses repository from this link: https://github.com/in-tech-gration/study-lenses/.
    • git clone git@github.com:in-tech-gration/study-lenses.git

  2. Change to the study-lenses directory and install all dependencies:

    • Run: cd study-lenses
    • Then: npm install (or npm i for short)

  3. Checkout to the lenses2 branch and run the npm link command to make this available globally:

    • git checkout lenses2
    • npm link
    • (or if you’re on a Mac/Linux, you’ll perhaps need sudo npm link)

  4. Check that study-lenses have been successfully installed on your system by running the following command:

    • lenses2 --version or lenses2 -v

Launching Study Lenses and following the material

Once lenses2 is properly installed on your system, you can go to your WDX-180 folder and run lenses2 with the material for this Module:

  • cd WDX-180/
  • lenses2 curriculum/modules/javascript/denepo/_just-enough-javascript/

or just:

  • cd WDX-180/curriculum/modules/javascript/denepo/_just-enough-javascript/
  • lenses2

Here’s a basic methodology for going through the material:

  • 1) Read the related material and explore any external resources
  • 2) Study the inline code using the recommended lenses
  • 3) Go through the exercises and try to explore and comprehend the code using the suggested (enabled) lenses
  • 4) Feel free to experiment with more lenses!

Once you are inside an exercise of example code, once again use the recommended lenses displayed above the code to explore and understand the code:
