 # To the Max explainer

#1

The aim of this puzzle: Find the largest number in the `array` using a loop and the `larger()` function.

Walkthrough of the solution: To find the maximum of a list, you can compare the first 2 items and store larger one as the current maximum. Then you compare that current maximum to the 3rd item, and store the larger one. Then continue until you’ve compared each item to the current maximum. In the end, the maximum will be the largest value from the array.

The `larger()` function takes in 2 numbers and will output the larger one. The `maximum()` function starts by creating a `max` variable that will store the current maximum, but it will start at `0` for now. The loop will go through each item in the `array` and hold it in a variable called `num`. What we need to do is compare the `num` to the `max` and store the larger one as the new `max`.

Instead of `max = num`, we need to use `max = larger(max, num)`. You can also switch the order of the arguments.

Sample code solution:
(Tap below to reveal)

``````function larger(a, b) {
return a > b ? a : b;
}

function maximum(array) {
let max = 0;
for (let num of array) {
max = larger(max, num);
}
return max;
}
console.log(list);
console.log(maximum(list));
``````
