Improve our linter about mathsteps

oh! I didn't realize it's strict by default. Let's get rid of "use strict"; in those files then. Thanks :D

I am working on this

[evykassirer]

woo! thanks @biyasbasak

this is going to be so helpful

Is it still open and assignable? I can add the missing rules if needed.

[evykassirer]

yes please! thank you :)

[Raibaz]

I opened PR #107 about this, but I have some doubts about the 'use strict' line: if I enable the strict rule, linting gives errors on almost every file since use strict' is unnecessary inside of modules, since ES6 modules are strict by default.

How do you think we should handle this?

[evykassirer]

done!! until we find more rules we want to add haha.

but let's close this for now :)

thanks so much @biyasbasak and @Raibaz for making the mode more beautiful 😍
