    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:

    - Object.assign() method:
    : > var obj = { a: 1, b: 2 }
    : undefined
    : > var copy = Object.assign({}, obj)
    : undefined
    : > console.log(copy)
    : {a:1,b:2}

    You can learn more about njs:
