[nginx-announce] njs-0.6.0

[Dmitry Volyntsev]

Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

This release proceeds to extend the coverage of ECMAScript
specifications.

Notable new features:
- let and const declarations support
: >> fuction test() { x = 1; let x; }
: undefined
: >> test()
: ReferenceError: cannot access variable before initialization
: >> function test2() {const x = 1; x = 2; }
: undefined
: >> test2()
: TypeError: assignment to constant variable
