Package managers
Why do we need a package manager? Atomicity, repeatability, compartmentalisation. There are a options: npm, bower; but they're often conflated into apt-get, composer (PHP projects), pip, gems. Bower devs are planning to EOL it and replac it with npm.
mkdir new-project cd new-project npm init npm install left-pad ls ls node_modules npm install left-pad --save # adds deps to package.json rm node_modules -rf npm install # installs dependencies locally.
ES6
ECMAScript 6. ECMA = European Computer Manufacturers' Association. Microsoft used ECMA to rubber-stamp their "standards", since ISO and IETF actually required some standardisation and collaboration effort.
