Var vs function.

What is the difference between var x = true (result is boolean) and var x = function() { return true }. (Returns boolean..?) Both variable and function I can invoke on any time. My mind now is overheat. Var x and var x() or function x() - Where this ones are used?

Differences between Declarations and Expressions. Similar to the var statement, function declarations are hoisted to the top of other code. Function expressions aren't hoisted, which allows them to retain a copy of the local variables from the scope where they were defined. https://www.sitepoint.com/function-expressions-vs-declarations/
