Answer / Manoj Kumar Meena
var is function-scoped and has a global scope when not defined within a function. It can be reassigned and does not have block scoping.
let is block-scoped (only accessible within the curly braces) and can be reassigned.
const is block-scoped (only accessible within the curly braces) and cannot be reassigned.
