I thought this technique was such common knowledge that I kept waiting for the punchline in the article. It was a good reminder that even the simple stuff deserves to be written about and revisited every so often.

Lately I've been finding a thorough test suite to be better at documenting code than comments. But I have to chuckle at "self documenting" every time I hear it.

The reason TODOs have survived the test of time is that bug trackers come and go while source code sticks around.

Google has the name to attract strong programmers. I'd like to see stats on how few (or many) strong programmers their interview process misses. Especially when that interview process is used at a company without such a huge name.

I agree now that what Eric Elliot is doing is not composition. But it's not inheritance as it is commonly known either. If I inherit from a prototype, then inherited objects can use the prototype methods via prototype delegation. If I

I can get foo.author.title and foo.post.title no problem using Object.assign: Object.assign({}, { author: author }, { post: post }); Can you give a better example of where a reference to an instance is any different than copying an i

Thanks for the article, it's a long read that requires some thinking so I'll get to it tomorrow. In the meantime I'll put a Kyle Simpson chapter out there as a rebuttal to "there is not a single disadvantage introduced w

How is Object.assign not a "has-a relationship"? From the first article you posted, this example of composition was given: { author: createAuthor(), posts: createPosts() } How is that different from this? O

It's sort of wrong, but not really if we are using the commonly used definition of inheritance where we think of the strict hierarchical inheritance provided by classes. And you mention prototype delegation which is only one type of in

Classes enforce a strict hierarchical relationship which is rarely how the real world works. And you also inherit everything from a parent class whether you need it or not. One alternative to class inheritance possible with javascript is ob

Encouraging inheritance in the first place is the mistake. Using composition with Object.assign is far less fragile than inheritance. An article with concrete examples: https://medium.com/javascript-scene/master-the-jav

Good naming is hard because you are using the wrong tool. Names in code, and even in the business world, are usually abbreviations for much more complex things. You should not be looking for too much meaning from the name itself. Most wor

Coursera offers a course about "Learning How to Learn" which I found very helpful. Once you understand what's happening in the brain it can motivate you to do what works (e.g. spaced repetition). In that course, they talk abo

Java would be an example of a language with weaker OOP capabilities. Javascript can emulate classic OO inheritance and it also supports prototypical inheritance. Crockford covers this in his Good Parts book, and you can find stuff around th

Could you give a concrete example? Why wouldn't you be able to use first-class functions when building something up from user input? How about giving us a code snippet? The consensus in the CS community is that the command pattern disa

The command pattern is featured in the article. Why would you use that pattern in a language that supports first-class functions?
