Syntax Preview

Tutor: JavaScript is the language of the web. The basic syntax starts with variables. We use 'let' for values that change and 'const' for constant values.

Variables and Types

In JavaScript, we declare containers for information.let allows the value to be changed, whileconst is for data that remains the same.

Strings: Text like "Hello World".
Numbers: Values like 42 or 3.14.
Booleans: Only true or false.

Challenge: Statement Order
