  10. Coding Challenge #javascriptFunctions

    Challenge 1

    Create a function expression with mainFunc as the variable name, which takes only one parameter of function type and calls that function inside the mainFunc.

    Hint: create a secondary function that has a simple console.log method with any string.

    Challenge 2

    Create a function addNum which takes 2 parameters. The first is an integer value and the other is a function type parameter. When addNum is invoked(called), it should return the sum of the first parameter and the return value from the second parameter(which is 10 here).

    Hint: the second function should return 10.

    Challenge 3
