javaScript Statements

In programming, a Statement is a line of code that performs a specific action. JavaScript statements are the building blocks of any script, enabling developers to create complex logic and execute tasks.

JavaScript statements are the backbone of any JavaScript program, providing the means to declare variables, make decisions, repeat tasks, and create reusable functions.

In the below PDF we discuss about Javascript Statements in detail in simple language, Hope this will help in better understanding.


Common Types of Javascript Statements:

1.  Declaration Statements:

Variables and constants are declared using statements. For example:

let name = "John";
const pi = 3.14;

2. Assignment Statements:

These statements assign values to variables. Here’s an example:

 let x = 10;

3.Conditional Statements:

Conditional statements control the flow of a program based on certain conditions. The if, else if, and else statements are crucial for decision-making in your code:

let age = 25;

if (age >= 18) {
console.log("You are eligible to vote");
} else {
console.log("Sorry, you are not eligible to vote");

4. Loop Statements:

Loop statements, such as for and while, allow you to execute a block of code repeatedly:

for (let i = 0; i < 5; i++) {
console.log("Iteration:", i);

5. Function Statements:

Functions are essential in JavaScript, and function statements define reusable blocks of code:

function greet(name) {
console.log("Hello, " + name + "!");



Understanding statements in JavaScript is fundamental to becoming a proficient developer. Whether you’re declaring variables, controlling program flow with conditionals, or implementing iterative processes with loops, statements are the tools that shape the logic of your code. As you continue your journey in JavaScript development, mastering the art of crafting effective statements will empower you to build robust and dynamic web applications. Happy coding!
