  1. Code Reuse in Node.js (the short version) ⺩王浩宇 Makara Wang

    [email protected] 2013.04.20

  2. Assuming you know... JS & Node.js Prototype “this”

  3. Common ways... Function + Arguments Good for: everything, promise, ...

  4. Common ways... Prototype + Class Good for: modeling... ...or you

    really care about performance ...or you want the long prototype chain

  5. Common ways... Function Copy this[key] = that[key]; Good for: simpler

    syntax, better syntax, ...

  6. My favorite Function Copy ...with “Object.defineProperties()” Because it’s Node.js (not

    a broken browser)

  7. Implementations https://github.com/medikoo/es5-ext require('es5-ext/lib/Object/extend-properties'); https://github.com/devo-ps/carcass carcass.mixable(obj);

  8. (Personal) Notes Use “this” Return “this” Reduce arguments Avoid “bind()”

    ...

  9. Thanks!
