  1. Hello everyone, please help the newbie figure it out. There is such a JS code. function makeDouble (x) { return x * 2; } var doMath = (x, func) => func(x + 5); var num = 5; The task is this: Using only makeDouble, doMath, and num, make the value of num equal to 20. num = _____________________________________________________ I can’t understand why there are two parameters in the arrow function, but in the body of this function itself there is only one parameter. What am I doing wrong?
