    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
