Comment by Marco Alka on "Which Javascript is good to have: Angular 5/Node.js/Both? How to install them?"

Your question is like asking: Which car is good to have: Apple AirPower or golden knobs for the radio or both?

Neither of your choices are "JavaScript", you might first want to google a definition for the things you want to use. Neither of the choices are useful to a beginner or required to develop with JavaScript.

tl;dr:

JavaScript is a programming language. You can use it to write programs
Angular is a framework, written in JavaScript and designed to solve a specific kind of problem. If you do not have that very problem, do not use Angular.
NodeJS is a program which can execute JavaScript programs and offers certain kind of interfaces to the programs it executes. You can use it to run your very own programs, if you want to execute them on your computer instead of in the browser; and if you need the interfaces it provides

I recommend reading The "I Am New To Programming" FAQ. It will help you get started with any programming language, including JavaScript and kinda guides you through your initial questions. Also, programming means a lot of googling for stuff, so you might want to practice that a bit ;)
