Hi, just a little question ; when you said, a variable declared in the middle of a function is in fact automatically declared at the top of the function, what is the "middle" ? Is it an if block, a while block or a for block ?
Also the hoisting concern just JavaScript or also others programing languages ?
Thanks

That's no a common thing as far as I know. I don't think Java, C++, Python or Ruby do that.

Say you have multiple lines of code in your function and declare a new var somewhere (in the middle) of all this code, it's like you had declared it on top of the function. So JS doesn't care where you define it, it only cares where you Change it's value. Another quick example. A new variable that is declared at the bottom of a function can be altered in the top.
