Prefer const over let where possible (tslint)
I generally prefer to use const
instead of let
whenever it is possible (this possibly is only my personal opinion). I added the rules
"no-var-keyword": true,
"no-for-in-array": true,
"no-inferrable-types": true,
"prefer-const": true,
to tslint
to enforce these rules. The changes are the automatically applied fixes for these rules.
