Second challenge #2

Jess2896 · 2019-09-26T15:25:23Z

Calculates which team has the highest average score and prints the result in the console.
The extra part of this challenge consisted on adding a third team and determining which of the 3 has the highest average score.

Verification steps

Download both files(index.html and script.js) into a folder and then open the index.html file on a browser.
Inspect the website and open the console to see the result obtained.

I think we can update the conditions, but first I would like to read if you have another approach to change these conditions.

The other option i can think of is to save the possible results in variables so the code is easier to read.

Can we store the winner on some kind of structure like an object so we don't need to repeat the string so many times?

Changed it, is it fine like this?

I think you should re-check this definition.
Can you give me some inside about let, const and var?

The main difference between var and let is that let is block-scoped instead of function-scoped, which is considered a better coding practice. Let also doesn't allow you to access a variable before its declared.

On the other hand, const is similar to let, the difference being that you can't assign a new value to the variable.

I realized I should have declared the scores as const since I don't need to change these values. Fixed the code.

On Es6 were introduce the template literals. We can use it here instead of storing the complete string value; just need to put it twice in case there was a tie.

Are you sure you want to change the base?
