Update

[nd0ut]

Changed rules:

• Throw error when using ==
• Do not throw error when reassign variables like: acc, res, req, e.
• Allow 'x', 'y', 'e', 'i', 'j' variable names
• Increase max-nested-callbacks from 2 to 3
• Increase max-params from 3 to 4
• Increase max-statements from 10 to 12
• Allow inline comments because It is sometimes faster and more obvious to put comments immediately following code (c) eslint docs
• Allow ++ in for loops
• Indent 2 spaces inside switch-case
• Throw error when using undefined variables

Added react rules from https://github.com/uploadcare/webclient-frontend

@Zmoki @bautrukevich
Do you have any suggestions that should be added to this PR? I mean can you remember any rules that you would like to enable, disable or change?

[bautrukevich]

If we can I want to change the rule for switch and add tabulation for case as normal.

And one more thing: "Allow 'x', 'y', 'e', 'i', 'j' variable names" — may be keep only x, y, i? I think we don't need a lot of this short variables.

[bautrukevich]

e — it's for event? j – for iteration? we don't have and maybe don't need to have more than 1 iterator in 1 file.

@bautrukevich yep, e for event, i,j for iteration. I would also add a,b or even disable this rule at all as airbnb did.
