»length Function

length determines the length of a given list, map, or string.

If given a list or map, the result is the number of elements in that collection. If given a string, the result is the number of characters in the string.

»Examples

> length([])
0
> length(["a", "b"])
2
> length({"a" = "b"})
1
> length("hello")
5

> length([])
0
> length(["a", "b"])
2
> length({"a" = "b"})
1
> length("hello")
5

When given a string, the result is the number of characters, rather than the number of bytes or Unicode sequences that form them:

> length("👾🕹️")
2

> length("👾🕹️")
2

A "character" is a grapheme cluster, as defined by Unicode Standard Annex #29. Note that remote APIs may have a different definition of "character" for the purpose of length limits on string arguments; a Nomad provider is responsible for translating Nomad's string representation into that used by its respective remote system and applying any additional validation rules to it.
