JavaScript Essentials for Node-RED course

“The instructor simplified complex concepts well.”

Shady Bahaa, Electrical Power Engineering Student
What you will learn

Everything you need to write better function nodes.

Every concept is explained for Node-RED, with plenty of practice along the way.

01

Variables and operators

Start from scratch with the building blocks of every program.

02

Arrays and objects

Store multiple values of the same or different data types.

03

Logic statements

Use IF-ELSE and switch-case to create multiple paths in your code.

04

Loops

Use while, do-while, for, for-in and for-of loops.

05

Functions

Create functions, call them with parameters and build nested functions.

06

Built-in methods

Use JavaScript's built-in methods for cleaner, more efficient code.

Is this the right course?

Don’t take our word for it.

“I’m really enjoying this course. it’s rare to find a JavaScript course focused on Node-RED and industrial protocols. Most JavaScript courses only cover web development, but this one bridges both worlds perfectly.”

Andrei Moreira
Engineering Student

“I am halfway through the Java Script Essential Course. I used to know nothing about it, and kinda hate it whenever I see it. You made me ‘Love it’.”

Saed Alhabbashi
