Hello,
I'm glad to announce a new release of NGINX JavaScript module (njs).
This release proceeds to extend the coverage of ECMAScript
specifications. Apart from specs conformance fuzzing under
Memory-Sanitizer is introduced which allowed to catch new types of bugs.
Notable new features:
- Shorthand method names (ES2015):
: > ({foo(){return 123}}).foo() // ({foo:function(){return 123}})
: 123
- Computed property names (ES2015)
: > ({['b' + 'ar']:123}).bar
: 123
- added getter/setter literal support:
: > ({get foo(){return 123}}).foo
: 123
: > ({get ['f' + 'oo'](){return 123}}).foo
: 123
