excerpt: JavaScript variables can be declared a handful of ways. However, they're not all created equal and understanding their differences can drastically change the way you code. excerpt: JavaScript variables can be declared a handful of ways.

JavaScript has three variable declaration statements: `var`, `let` and `const`. The latter two were added in ES6, whereas `var` existed since previous versions. One of the first things to notice is that `const` defines constants (i.e. values that will not be reassigned), whereas `var` and `let` define variables. Yet, `var` behaves differently from both `let` and `const` in various other ways. JavaScript has three variable declaration statements: `var`, `let` and `const`.
