I'm a bit confused about how the answer is coming out to be 15 in this scenario. I do understand that the function scope of doSomething involves calling doSomethingElse, but my calculation isn't leading me to the same result as 15.
function doSomething(a) {
b = a + doSomethingElse( a * 2 );
console.log( b * 3 );
}
function doSomethingElse(a) {
return a - 1;
}
var b;
doSomething( 2 ); //15
There is no scope boundary being crossed in the code provided:
1. doSomething(2);
2. b = 2 + doSomethingElse(2 * 2);
3. b = 2 + (2 * 2 - 1);
4. b = 2 + 3
5. b = 5;
6. console.log(b * 3);
7. console.log(5 * 3);
8. console.log(15);
9. 15
