Remember, that the only stated purpose of using var, according to the language designers (since JDK 10+), has been the point to beautify the code and make it more readable (which, I personally think, is a non-sense as having "var" in Java, is worse than having explicit types, and in many ways so).
- c# - How to initialize var? - Stack OverflowC# is a strictly/strongly typed language. var was introduced for compile-time type-binding for anonymous types yet you can use var for primitive and custom types that are already known at design time.

- javascript - var functionName = function() {} vs ... - Stack OverflowThe sentence "due to hoisting" might give a wrong impression that only the named function gets hoisted. In fact, both var functionOne as well as function functionTwo get hoisted to some degree - it's just that functionOne is set to undefined (you could call it half-hoisting, variables always get hoisted only to that degree) whereas function functionTwo is fully hoisted in that it's defined and ...
- What is the difference between "let" and "var"? - Stack OverflowThe use of "let" just defers this problem. So each iteration creates a private independent block scope, but the "i" variable can still be corrupted by subsequent changes within the block, (granted the iterator variable is not usually changed within the block, but other declared let variables within the block may well be) and any function declared within the block can, when invoked, corrupt the ...
