What is the difference between Let and Var ?

Question

Lesson does not show clearly the differences between Let and Var .

Answer 1

Oops.. sorry, missed that tag, could've helped if it says "Swift" rather, sorry everyone :)

Answer 2

Haha.. @Ipang, I made the same mistake too, always thought that let and var belong to JavaScript. I deleted my answer now.. 😜

Answer 3

It clearly shows the difference. let indicates constant variable, which is not to be changed. var is just regural variable.

Answer 4

let creates a constant. Once the value is set to a let identifier it cannot be changed unlike a var.

Answer 5

Ok !!!
thanks

I had understood constant was entered with Int.

Answer 6

@Ipang Swift not Javascript.
let is different in Swift then it is in Javascript.
