In an algebra of functions, dealing with functions that take multiple arguments (or equivalent one argument that's an N-tuple) is somewhat inelegant -- but, as Moses Schönfinkel (and, independently, Haskell Curry) proved, it's not needed: all you need are functions that take one argumen...
In the first code example we are instantiating SpellChecker (this.checker = new SpellChecker();), which means the TextEditor class directly depends on the SpellChecker class. In the second code example we are creating an abstraction by having the SpellChecker dependency class in TextEditor's con...

This is the stage where the physical and virtual hardware that the applications will run on are managed and provisioned. These days, many operations professionals only deal with abstractions on top of pools of those physical machines. Configuration Management ...
in principle be so precisely described that a machine can be made to simulate it,” McCarthy and his coauthors wrote. “An attempt will be made to find how to make machines use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves...
Variable names can help remove some of the subtle abstractions inherent in code. For example, http parameters in the Ruby on Rails framework are parsed from multiple sources (query parameters, url segment parameters, form input parameters) into a single hash called params. When using the params ...
Operating System:The operating system is responsible for managing resources, providing abstractions for hardware components, and enabling programs to run on the hardware. C code can interact with the OS through system calls. I/O Devices:C code can interact with input and output devices like keyboar...
Are existing variables being used where they should be? Have new variables been introduced? If so, do they make sense and are they documented? Were other abstractions (e.g. extends, mixins, loops, maps, etc) used effectively and in adherence with how the rest of the code is doing things...
of it like a contract or a blueprint. It specifies the methods or behaviors that must be available without dictatinghowthey should be carried out. (Whiledefault interface methodsare a special case in modern languages like C#, they don't change the fundamental role of interfaces as abstractions...
I'm pretty much all JavaScript, all day every day. Specifically, I prefer to work on lower level API stuff, writing abstractions and tools to build other stuff on top of, such as event systems, promises, and XHR/data IO frameworks. I try very hard to make APIs that are intuitive, fle...
