Linter warnings

[lexoyo]

We should cleanup the code to remove linter warnings, i.e. do npm run lint and fix the warnings

Good idea but most of the warnings are not trivial :

• no-console, meaning we need to choose a logger strategy
• no-alert, basically the same thing
• class-method-use-this, meaning we need to refactor some classes to use static methods as much as possible

So this will be needed soon, but not sure it's a good first issue 😉

Hello Jb ! Maybe could I just delete the console.log ? Alex told me it should be enough to fix this issue.

Hello @louisauve and welcome in this project! If @lexoyo said they're not needed, remove them 😃

I reopen this issues as there are still warnings and even a few errors, am I right?
