Not recommended to use anymore - use let or const instead. 👎
Used to declare variables within a function scope. Variables declared with var can be both
- updated
- re-declared
It can also be just constructed, and the value would be
undefined
var myName = "Jane";
myName = "Shakib" // (Update) myName will return Shakib
var myName = "Impostor" // (Re-declare) this is allowed for vars
var whaT;
console.log(whaT) // returns 'undefined'
