Variables in standard JavaScript have no type attached, so any value (each value has a type) can be stored in any variable. Starting with ES6, the 6th version of the language, variables could be declared with var for function scoped variables, and let or const which are for block level variables.
So if you have nested functions, it is possible to use a variable without instantiating it with var but not be available globally, if there is an outer function in which that variable is defined. This is one of the concepts that make closures in JavaScript possible. 24.49.69.72 17:50, 7 April 2007 (UTC) [ reply ]
