Hash

people = [{"name": "Anna", "age": 24}, {"name": "Bob", "age": 99}];

// reassign of values
h = {"a": 1, 2: true}
puts(h["a"])
puts(h[2])
h["a"] = 3
h["b"] = "moo"
puts(h["a"])
puts(h["b"])
puts(h[2])h = {"a": 1, 2: true}
puts(h["a"])
puts(h[2])
h["a"] = 3
h["b"] = "moo"

// should output
1
true
3
"moo"
true

Literal Specific Methods

get(INTEGER|STRING|BOOLEAN|ARRAY|HASH|FLOAT|ERROR|NIL, INTEGER|STRING|BOOLEAN|ARRAY|HASH|FLOAT|ERROR|NIL)

Returns INTEGER|STRING|BOOLEAN|ARRAY|HASH|FLOAT|ERROR|NIL

{"a": "1", "b": "2"}.get("a", 10)
{"a": "1", "b": "2"}.get("c", 10)

Output

1
10

include?(BOOLEAN|STRING|INTEGER|FLOAT|ARRAY|HASH)

Returns BOOLEAN

Returns true or false wether the hash contains the given object as key

{"a": 1, 1: "b"}.include?(1)
{"a": 1, 1: "b"}.include?("c")

Output

true false

keys()

Returns ARRAY

Returns the keys of the hash.

{"a": "1", "b": "2"}.keys()

Output

["a", "b"]

values()

Returns ARRAY

Returns the values of the hash.

{"a": "1", "b": "2"}.values()

Output

["1", "2"]

Generic Literal Methods

methods()

Returns ARRAY

"test".methods()

Output

["upcase", "find", "format", "reverse", "split", "replace", "strip!", "count", "reverse!", "lines", "downcase!", "upcase!", "size", "strip", "downcase"]

to_f()

Returns FLOAT

If possible converts an object to its float representation. If not 0.0 is returned.

1234.to_s()
1234.to_s(2)
1234.to_s(8)
1234.to_s(10)
"test".to_s()
1.4.to_s()
