JavaScript Syntax
Prerequisites: Your first JavaScript program
Unlike Python, JavaScript uses curly braces { } to group a block of
code, not indentation — though consistent indentation is still expected
for readability.
if (true) {
console.log("This line is inside the if block");
console.log("So is this one");
}
console.log("This line is not — it always runs");
Statements typically end with a semicolon ;. Whitespace and
indentation are purely cosmetic — they never change what the code does.
