Length

Description

The length function takes a string, list, or map, and returns the count of characters or items.

Syntax

length(string text)

length(list myList)

length(map myMap)

• text is the string whose length to calculate.
• myList or myMap are collections whose items to count.

Remarks

• For text, each whitespace counts as one character. So, two spaces are two characters, a line break is one character, and so on.
• For text, the length is the number of so called grapheme clusters, not the number of bytes. So, a single character can be multiple bytes. For example, '🤷‍♂️' is treated as one character, not 5.

Examples

length("Hello!")                   // 6
length([1, 2, 3, 4])               // 4
length({ "a": 1, "b": 2, "c": 3 }) // 3

length("🤷‍♂️")                      // 1
