🍩Plus (+) operator

In JavaScript, the + operator is used for addition and string concatenation.

For example:

let x = 1 + 2; // x is 3
let y = 'Hello' + ' World'; // y is "Hello World"

The += operator is a compound assignment operator that is used to add a value to a variable and assign the result to that variable. It is a shorthand version of writing variable = variable + value.

For example

let x = 1;
x += 2; // x is now 3

let y = 'Hello';
y += ' World'; // y is now "Hello World"
