hoisting means things within a scope are moved up.
It's a term related to compilation execution, because it means a block is parsed completely before it starts running it, and the exact ordering doesn't matter.
In JS, declarations (variable declarations and function declarations) are hoisted, meaning you can use them.
A potentially confusing thing is that depending on the language, declaration may be hoisted but initialisation is not, so var i=0 is two things possibly done at two different times.
