'var' is used instead of 'let' or 'const'
Reports a var declaration that is used instead of let or const.
Both let and const are block-scoped and behave more strictly.
Suggests replacing all var declarations with let or const declarations, depending on the semantics of a particular value. The declarations may be moved to the top of the function or placed before the first usage of the variable to avoid Reference errors.
Select the 'Conservatively convert var with Fix all action' option to prevent any changes in these complex cases when using the 'Fix all' action.
