In this article, we will see how to declare multiple Variables in JavaScript. The variables can be declared using var , let , and const keywords. There are different methods to declare multiple variables, these are:

Declaring Variables Individually: In this case, we will declare each variable using the var, let, or const keywords.

Syntax:

let x = 20;
let y = 30;
let z = 40;

Example:

Javascript

let x = 20;
let y = 'F';
let z = "Freesad";
  
console.log("x: ", x);
console.log("y: ", y);
console.log("z: ", z);

Output
x:  20
y:  F
z:  Freesad

Declaring Variables in a Single Line: You can declare multiple variables in a single line using the var, let, or const keyword followed by a comma-separated list of variable names.

Syntax:

let x = 20, y = 30, z = 40;

Example:

Javascript

let x = 20,
    y = 'F',
    z = "Freesad";
  
console.log("x: ", x, "\ny: ", y, "\nz: ", z);

Output

x:  20 
y:  F
z:  Freesad

Using Destructuring Assignment: You can also use de-structuring assignments to declare multiple variables in one line and assign values to them.

Syntax:

const [var1, var2, var3] = [val1, val2, val3];

Example:

Javascript

const [x, y, z] = [20, 'F', "Freesad"];
  
console.log("x: ", x, "\ny: ", y, "\nz: ", z);

Output
x:  20 
y:  F
z:  Freesad
