The Map collection in F# is an immutable Key/Value collection. Let's learn how to work with them! === Contact === Email: hi@fastfsharp.com Mastadon: mastodon.sdf.o... Twitter: / fastfsharp === Tags === Tags: #fsharp, #dotnet
Great explaining as always. This is interesting. This is not even complaining. Its just removing the first bit and replacing it with the last one. let a = Map [ 1, "a"; 2, "b";1,"c" ] a[1] > let a = Map [ 1, "a"; 2, "b";1,"c" ] - a[1];; val a: Map = map [(1, "c"); (2, "b")] val it: string = "c" But why ist that?
Because when you are creating a map, the "last write wins". If you have several instances of the same key, that last key/value pair will be what is stored in the Map.
