? JavaScript Statements

Statements are the instructions that tell the browser what to do. They are like sentences in the JavaScript language.

What is a Statement?

• A complete unit of execution.

• Ends with a semicolon (;) — though it’s often optional.

• Can be simple or complex (like if, for, while, function declarations).

Types of Statements

1. Expression Statements

• Execute an expression.

let x = 5;x = x + 1;console.log(x);

2. Conditional Statements

• Control flow based on conditions.

if (x > 5) {  console.log("x is greater than 5");} else {  console.log("x is 5 or less");}

3. Loop Statements

• Repeat code multiple times.

for (let i = 0; i < 5; i++) {  console.log(i);}

4. Declaration Statements

• Define variables or functions.

var name = "Alice";function greet() {  console.log("Hello!");}

5. Jump Statements

• Change the flow abruptly.

break;   // exit a loop or switchcontinue; // skip to next loop iterationreturn;   // exit a function and return a value

Example: Multiple Statements

let sum = 0;for (let i = 1; i <= 5; i++) {  sum += i;          // expression statement}console.log(sum);    // expression statement

Summary

• Statements perform actions.

• They can be simple or compound (blocks).

• JavaScript programs are made of sequences of statements.
