Code Inspection: 'var' used instead of 'let' or 'const'
var declarations that are used instead of
const are block-scoped and behave more strictly.
It helps to replace all
var declarations with
const declarations, depending on value semantics. Declarations might be moved to the top of the function or before the first usage of the variable to avoid Reference errors.
Check Conservatively convert var with Fix all action option to prevent any changes in these complex cases when using Fix all action.
