Use the browser developer console to execute simple JavaScript expressions.

Declare variables using let, const, and var, and explain the differences in scope and reassignment.

Identify and use primitive data types: string, number, boolean, null, and undefined.

Use arithmetic, comparison, and logical operators to form complex expressions.

Explain the concept of type coercion and use the `typeof` operator to determine a value's type.

Create and interpret template literals with embedded expressions for dynamic string creation.

Use `console.log()` to output values and debug simple logical errors in a program.
