Improved
v1.8.0.beta1
Highlights
Hash is now bridged to JavaScript Map
This change brings a lot of benefits, but also some incompatibilities. The main benefit is that Hash now is both more performant and relies on native JavaScript capabilities.
This improves interoperability with JavaScript. As a downside, applications reaching for internal Hash data structures will need to be updated.
Interacting with Hash from JavaScript is easier than ever:
hash = `new Map([['a', 1], ['b', 2]])`
hash # => {a: 1, b: 2}
`console.log(hash)` # => Map(2) {"a" => 1, "b" => 2}
`hash.get('a')` # => 1
`hash.set('c', 3)`
hash # => {a: 1, b: 2, c: 3}
hash.keys # => ["a", "b", "c"]
hash.values # => [1, 2, 3]
Performance improvements
This release brings a lot of performance improvements, our tests on Asciidoctor show a 25% improvement in performance, but we've seen up to 66% performance improvement on some applications.
