I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.

Question: If a newcomer to JavaScript asked you for essential libraries and tools, what would you tell them? You don’t want to overwhelm them with too many suggestions!

Focus: language-related functionality (as opposed to browser-related functionality).

• Libraries: including, say, Underscore.js and promises libraries, but excluding jQuery et al.
• Tools: package managers, build tools, unit test tools, etc.
  • Less important: editors, IDEs. Rationale: it’s fairly obvious that you need them. There are other tools that people might not even know that they need.

// OOP
console.log( 'OHAI'.blink() );

// Call invocation
console.log( String.prototype.blink.call('OHAI') );

// $ always makes things look awesome.
var $ = Function.prototype.call;

// Very explicit call invocation
