Consider following code snippet:


var a = 2
var x  = 1 + (a*=2)

What will be the value of x variable after executing the code?

Correct answer is 5

var a = 2;
var x  = 1 + (a=a*2);
console.log(x); //the result will be 5 because a*=2 is the same as a=a*2

and x = 1+4 = 5

I think that it is better to explain like this. var a = 2; var x = 1 + (a=a*2); console.log(x); //the result will be 5 and a*=2 is the same as a=a*2
