Javascript for Lightning Web Components [FREE]

Is this the right course for you?

Build the JavaScript foundation you need before working through Lightning Web Components examples. This free course is a starting point for learners who can follow a web page but want to understand the language behind its behavior. Use the episode list to work through the concepts in sequence.

Before you start

A browser console or a simple local JavaScript environment is enough for practicing language concepts. Basic HTML knowledge is useful, but you do not need to start with a complete Salesforce application. Focus on understanding what each expression evaluates to before adding framework-specific behavior.

Put the lessons into practice

After each lesson, write a small example from memory. Change the inputs, predict the output and check your prediction in the console. When you move to LWC, identify which parts are ordinary JavaScript and which are Salesforce APIs, so debugging starts at the correct layer.

Use the syllabus below to choose your next lesson. Pause as you go, reproduce the example, and check your result before continuing. This makes the lesson a practice session you can repeat, rather than a video you only watch once.
