On this post I would continue to add my notes on JavaScript Build Tools, Its like commands, concepts, packages or anything around it.

Gulp.js automates build related tasks for web based frontend stuff e.g.  :

• Minification
• Concatenation
• Less to CSS compilation
• Optimising 3rd party and custom code
• Injecting files into HTML
• File revisions and versioning
• Caching Angular Templates
• Testing
• Code Analysis

Yarn : Manage Javascript Dependencies e.g. Install libraries, packages, and applications

• Developer Tools
• Web Technologies
