String

Join

Join(parts~: string[], separator?: string) -> string

The parts as one text, with separator between them. Without a separator they are run together.

parts~ converts: each value in parts becomes a string before Join runs, so a number, a boolean or a null there needs no conversion op.

output label = Join(["Bus", "7"], " ")

label

"Bus 7"

output code = Join(["A", "B", "C"])

code

"ABC"

Upper(text: string) -> string

The text in upper case.

output shout = Upper("live")

The text in lower case.

Trim

Trim(text: string) -> string

The text without the spaces at its start and end.

StartsWith

StartsWith(text: string, part: string) -> boolean
