values

values(map | null) -> list

What it does

The values of a map as a list, in the order the entries were added. Each value is itself, whatever its type: a nested map or list is not copied or flattened. null counts as an empty map and gives [].

Examples

let prices = { apple: 2, pear: 3, fig: 5 }print(values(prices))print(values(prices) | sum)

[2, 3, 5]10

Edge cases

• Order follows keys: values(m)[i] belongs to keys(m)[i], in the browser too, keys that look like numbers included.
• A null value stays in the list; nothing is dropped.
• An empty map and null both give [].

let m = { a: [1], b: { c: 2 }, d: null }print(values(m))print(zip(keys(m), values(m)))print(values({}), values(null))

[[1], { c: 2 }, null][["a", [1]], ["b", { c: 2 }], ["d", null]][] []

Errors

Anything but a map or null is a runtime error, not an error value.

print(values("ab"))

line 1: `values` expects a map as argument 1, got str

Chaining

print({ a: 3, b: 1, c: 2 } | values | sort)print({ a: 1, b: 2 } | values | map((v) => v * 10))

[1, 2, 3][10, 20]
