Function in js

Function
Function is a block of code designed to perform a specific task. It executes only when it is called (invoked).

  - Code reusable
  - Declare code once,use it whenever we want
  - Call the function to execute the code

Syntax

function functionName() {
// Code to execute
}

Example

function ammatea(){
    console.log("Unoda Tea Ready");
}
ammatea();

Output:Unoda Tea Ready

Code Reusability
Write the code once and use it multiple times

function add() {
    console.log(10 + 20);
}

add();
add();
add();

Modularity
Divide a large program into smaller, manageable parts (modules/functions)

function login() {
    console.log("User logged in");
}

function displayProfile() {
    console.log("Profile displayed");
}

function logout() {
    console.log("User logged out");
}
