I see your TypeScript and raise you kotlin:

var a: String
[–] uranibaba@lemmy.world 1 points 2 weeks ago (4 children)

What’s up with that syntax? Why the use of var here?

[–] DmMacniel@feddit.org 3 points 2 weeks ago* (last edited 2 weeks ago) (3 children)

Kotlin knows mutable and immutable variables. var indicate mutables and val would indicate immutables (comparable with the final modifier in java and const in JavaScript/TypeScript).

So a var can start as a string and later be an integer?

[–] DmMacniel@feddit.org 2 points 2 weeks ago

No, the type is strict and fixed.

I don't know Kotlin but in other languages "(im)mutable" refers to the value, not the type.
