Comma Operator

Comment

A comma operator takes two expressions, evaluates them from left to right, and returns the right expression's value.

/*
	// Syntax
	(leftExpression, rightExpression)
*/

let x = 10;
let y = (x++, x + 1);

console.log(x, y); // log 11 and 12

// It's equivalent to the code below; (more explicit)
let x = 10;
x++;
let y = x + 1

// With love @kouqhar

We increase the value of x by one (x++), add one to x (x + 1), and assign x to y. Therefore, x is 11, and y is 12 after the statement.
