I’m amazed that so many people immediately want to find the code that executes the fastest. If ONE MILLION iterations STILL take less than a second to process, is this going to be in ANY WAY noticeable to the end user? Not very likely. Premature optimization = FAIL. I’d go with the String.Format option, only … Read more
Note: the MVC and MVC-inspired patterns are advanced constructs. They are meant to be used in codebases where ordinary object-oriented (that follows SOLID and other guidelines) code starts to become unmanageable. By introducing this pattern you would impose additional constraints, which then lets you to contain very complex applications. MVC is not meant for “hello … Read more
The first way is easier to maintain. Each declaration is a single statement on a single line, so you can easily add, remove, and reorder the declarations. With the second way, it is annoying to remove the first or last declaration because they start from the var keyword and finish with the semicolon respectively. Every … Read more
like this: var foo = 45; var bar=”” + foo; Actually, even though I typically do it like this for simple convenience, over 1,000s of iterations it appears for raw speed there is an advantage for .toString() See Performance tests here (not by me, but found when I went to write my own): http://jsben.ch/#/ghQYR Fastest … Read more
I always use underscores. It creates a clear distinction between local variables and instance variables. It also avoids compiler warnings in the following situation: @interface MyClass { NSString *name } @property (nonatomic, copy) NSString *name; – (id) initWithName:(NSString *) name; @end @implementation MyClass @synthesize name; // The following method will result in a compiler warning … Read more
I’ve been building tools (DMS Software Reengineering Toolkit) to do general purpose program manipulation (with language translation being a special case) since 1995, supported by a strong team of computer scientists. DMS provides generic parsing, AST building, symbol tables, control and data flow analysis, application of translation rules, regeneration of source text with comments, etc., … Read more
I like to use double quotes around strings that are used for interpolation or that are natural language messages, and single quotes for small symbol-like strings, but will break the rules if the strings contain quotes, or if I forget. I use triple double quotes for docstrings and raw string literals for regular expressions even … Read more
It’s usually to namespace (see later) and control the visibility of member functions and/or variables. Think of it like an object definition. The technical name for it is an Immediately Invoked Function Expression (IIFE). jQuery plugins are usually written like this. In Javascript, you can nest functions. So, the following is legal: function outerFunction() { … Read more
I have been a vocal critic of these TRs since their inception (when it was a single TR) and would never use them in any of my software. They mask symptoms instead of addressing causes and it is my opinion that if anything they will have a negative impact on software design as they provide … Read more
Why is it considered a bad practice to omit curly braces? [closed]
