[](*args)
public
Creates a new hash populated with the given objects.
Similar to the literal { key => value, … }. In the first form, keys and values occur in pairs, so there must be an even number of arguments.
The second and third form take a single argument which is either an array of key-value pairs or an object convertible to a hash.
Hash["a", 100, "b", 200] #=> {"a"=>100, "b"=>200} Hash[ [ ["a", 100], ["b", 200] ] ] #=> {"a"=>100, "b"=>200} Hash["a" => 100, "b" => 200] #=> {"a"=>100, "b"=>200}

Assignment using 'key: value'
Another shorthand way of assigning key, value pairs:
Hash[one: 1, two: 2] #=> {:one=>1, :two=>2}

What is the purpose of
Hash[one: 1, two: 1]
When you can write
{one: 1, two: 2}
Aren’t you just passing a hash into the [] method?
