Javascript Lambda Expression Example

var xa = function(a) {
  return a;
}

var xl = a => a;

var x = () => { console.log("hi"); };
x();

//console.log(xl("hi"));


var sum = (a,b,c) => a+b+c;
console.log(sum(3,4,5));


setTimeout( function() { console.log("timeout");}, 200);
setTimeout(() => console.log("timeout lambda"), 200);


//function multiply(a,b) {
//  return a*b;
//}

var multiply = (a,b) => a*b;
console.log(multiply(2,3));

(() => {
   this.speed = 0;
   setInterval( () => {
     this.speed++;
     console.log(this.speed);
   }, 200
   );
})();
