Does any one have any project ideas to help with conditional statements and functions?

I'm looking to build a list of project ideas to help get down conditional statements and functions.

Depends on how comfortable you are with some of the other basic concepts of JS (i.e. loops, objects, arrays). I'd say try to mimic some of the functions that are already in JS. You'll have to use conditionals in those functions quite often so it will help you practice both. For instance:

// Returns the index of a value in an array
// If value isn't in array, return -1
function find(arr, value) {
    for (var i = 0; i < arr.length; i++) {
        if (arr[i] === value) {
            return i;
        } else {
            continue;
        }
    }
    return -1;
}

find([1,2,3], 3) // => 2
find([1,2,3], 5) // => -1

This function gives the same functionality as the Array.indexOf() method.

This exercise will help you in learning how to write functions and conditionals, while also helping you learn about some of the different functions and methods that are already available to in JS and how they work.

But like I said, you'll probably need to get mildly comfortable with all of the basics to really get into some of the more complicated native JS functions.
