eslint/no-regex-spaces Restriction 
What it does 
Disallow 2+ consecutive spaces in regular expressions.
Why is this bad? 
In a regular expression, it is hard to tell how many spaces are intended to be matched. It is better to use only one space and then specify how many spaces are expected using a quantifier.
