variable naming

[m4v15]

In your back end the variable names are good and quite explicit about what the code does.

But in front end, less so:

Carsdb/public/index.js

Line 1 in 121fb4d

const arrayres = (value) => {

what does arrayres mean? when I see this in dom.js I have to come and look at this file to know what it means. if it was named something like makeSuggestionsRequest then this would be much more clear.

Secondly

Carsdb/public/dom.js

Line 1 in 121fb4d

var carinput=document.getElementById('car');

Try to make sure you are using camelCase consistently in your code for variables
