Lesson 3: Control Flow and Decision Making

Introduction to Control Flow

By default, browser engines read your script top-to-bottom. However, real-world applications need to run code conditionally. We use [control flow] to guide our application based on input, state, or calculations.

To see more operational examples, check the documentation on W3C Standards or MDN.

Comparison Operators

Before writing conditional blocks, you must understand how values are compared:
* === Strict Equality (Checks both value and data type)
* == Loose Equality (Checks values only, attempts type coercion - avoid this!)
* !== Strict Inequality
* > Greater Than, = Greater or Equal, = 18 ? 'Adult' : 'Minor';).
