How to get length of array

Questions
1

I wish to display “teacher” when array length = 1, else “teachers”
The following snippet does not work in vscode:

#let team = [1, 2, 3, ]
#if team.len == 1 { "teacher" } else { "teachers" }

here is the command i ran to compile. I am using typst 0.13.1

PS C:\Users\user\typst> typst compile .\main2.typ
error: sequence does not have field "len"
  ┌─ \\?\C:\Users\user\typst\main2.typ:3:9
  │
3 │ #if team.len == 1 { "yes" } else { "asdadaaa" }
  │          ^^^

PS C:\Users\user\typst> typst --help
Typst 0.13.1 (8ace67d9)

even after changing to

#let team = (1, 2, 3, )
#if team.len == 1 { "yes" } else { "asdadaaa" }

it still does not work :

PS C:\Users\user\typst> typst compile .\main2.typ
error: cannot access fields on type array
  ┌─ \\?\C:\Users\user\typst\main2.typ:2:9
  │
2 │ #if team.len == 1 { "yes" } else { "asdadaaa" }
  │          ^^^

See array.len. It’s a function.

I got it. I have to write team.len() and not team.len

Here is the correct code:

#let team = (1, 2, 3, )
#if team.len() == 1 { "yes" } else { "asdadaaa" }

it compiles successfully
