Function List (11)

Function	Signature	Description	Example
keys	keys(objectValue)	Object keys.	{a:1,b:2} | keys -> ["a","b"]
values	values(objectValue)	Object values.	{a:1,b:2} | values -> [1,2]
entries	entries(objectValue)	[key, value] entries.	{a:1} | entries -> [["a",1]]
has	has(objectValue, key)	Property existence.	{a:1} | has("a") -> true
get	get(objectValue, path, defaultValue?)	Dot-path lookup with fallback.	{a:{b:1}} | get("a.b") -> 1
merge	merge(objectValue, ...objects)	Shallow merge.	{a:1} | merge({b:2}) -> {a:1,b:2}
pick	pick(objectValue, keys)	Keep only selected keys.	{a:1,b:2} | pick(["a"]) -> {a:1}
omit	omit(objectValue, keys)	Remove selected keys.	{a:1,b:2} | omit(["b"]) -> {a:1}
length	length(objectValue)	Number of object keys.	{a:1,b:2} | length -> 2
assign	assign(objectValue, source)	Object.assign-style merge.	{a:1} | assign({b:2}) -> {a:1,b:2}
isEmpty	isEmpty(value)	Empty check for object/array.	{} | isEmpty -> true

Notes

• get supports dot notation paths (for example "a.b.c").
• pick and omit require an array of keys.
• isEmpty treats non-object values as empty and arrays by length.
