This post is part of a series on the SOLID programming principles. Starting this post and for the following four Mainstay Monday posts, I am going to go through the SOLID principles as put forth by Bob "Uncle Bob" Martin and Michael Feath ...

With programming languages which have a greater draw for classically trained computer science types, there is a common discussion of contracts and data expectations. Contracts are so inherent in the code that it's hard to see a declaration ...

If you have been writing Javascript for any amount of time, you're sure to be familiar with standard loop structures. For and while blocks are part and parcel of the modern programming experience. On the other hand, if you haven't done a ...

If you've come from one of those big name, big OO frameworks, you are probably used to the idea of an Inversion of Control (IoC) container and dependency injection. If you have worked with Angular, you're probably familiar with their depen ...

If you are new to programming and, especially, to a dynamically typed language like Javascript you are likely not familiar with type coercion. The best way to think about type coercion is, when dealing with two values of different types, ...

It has been a really, really long time since I created a switch statement. I'm not saying there is no place for switch statements in programming, I'm just saying, I haven't had a reason to use one in a long time. Even though I haven't writ ...

Last week we kicked off a discussion of scope in source code. We talked about lexical scope and how that impacts the way variables are accessed. There is another element of scoping called contextual binding, which is what gives people the ...

A couple of my friends and I have the same conversation once or twice a month: How do you deal with content that could be displayed in any number of different devices? I know, this sounds like chilling lunchtime conversation, but this is ...

Edit: I incorrectly stated that Javascript has dynamic scoping. It actually uses a mix of lexical scoping and contextual binding. Dynamic scoping is significantly different than contextual binding. This post has been updated to reflect cor ...

Over the last year I have interviewed a lot of Javascript developers and I discovered something: many people working in Javascript don't really understand what programming really means. What I am saying by this is, people can write code an ...
