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;
Â
Example:
Javascript
let x = 20; let y = 'G'; let z = "neveropen"; Â Â console.log("x: ", x); console.log("y: ", y); console.log("z: ", z); |
Output
x: 20 y: G z: neveropen
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, Â Â Â Â y = 'G', Â Â Â Â z = "neveropen"; Â Â console.log("x: ", x, "\ny: ", y, "\nz: ", z); |
Output
x: 20 y: G z: neveropen
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, 'G', "neveropen"]; Â Â console.log("x: ", x, "\ny: ", y, "\nz: ", z); |
Output
x: 20 y: G z: neveropen
