If you declare a variable without using var , even if it’s inside a function, it will still be seen as global: JavaScript Function Scope. In JavaScript there are two types of scope: Local scope; Global scope; JavaScript has function scope: Each function creates a new scope. Scope determines the accessibility (visibility) of these variables.
