What's the difference of var and let?
Steven Parker225,726 Points
The keywords "var" and "let" both create new variables, with some slight (but often very important) differences. For example, "var" creates variables with function scope, and "let" creates them with block scope. Variables created with "var" are "hoisted", but those made with "let" are not.
For more details on these and other differences, see the MDN pages for var and let.
