Commit 701e38c
tools: enable prefer-const eslint rule
Description from: http://eslint.org/docs/rules/prefer-const.html
If a variable is never modified, using the `const` declaration is
better. `const` declaration tells readers, "this variable is never
modified," reducing cognitive load and improving maintainability.
