Whenever you are considering a style question, ask yourself: But it reduces clutter, and I expect engines to eventually optimize this pattern. If you use methods generically, you can abbreviate Object. Prefer constructors over other instance creation patterns I recommend that you: In the latter case, they return a value and while there is a mnemonic, you still need to think to metavode out what is going on: A Meta Code Style Guide.
It should tell you how to get started with the code base mstacode provide you with the big picture.
Code Should Be Consistent. It has been inherited from Java and most style guides recommend it.
First, familiar things are easier to understand. Second, humans read tokens, not characters. Documentation should fill in the blanks left by the code and the comments. So if you are as clever as you can be when you write it, how will you ever debug it? Changing undefined explains why. To write such code, use descriptive identifiers and mrtacode up long functions or methods into smaller subfunctions.
The rationale is that this is what a named function expression looks like if you remove the name: In modern engines, using instances of constructors is very fast e. If those functions are small enough and have meaningful names, you can often avoid comments. Thus, there is no need to write yet another one. This helps with reading, because it is easier to make out the scope of the operator: Three parts of a code base help: However, you have to find ways to recover gracefully from failure when your code is in production.
The bodies of control flow statements are always put in braces, even if there is only a single statement. Always use new when creating an instance. Code Should Be Easy to Understand.
Initializing an array with elements avoid!
Meta Imaging Series Codes
It is also easier to remove the code fragment or to move it somewhere else. Sometimes you have no choice but to optimize the performance of your code.
The advantages of this approach are that deleting, inserting, and rearranging lines is simpler and the lines are automatically indented correctly. Commonly Accepted Best Practices. If you return an object literal, you must put the opening brace in the same line as the keyword returnlike this otherwise, automatic semicolon insertion inserts a semicolon after returnmeaning that nothing is returned; see Pitfall: More tips for using constructors are mentioned in Tips for Implementing Constructors.
These are style guides that I like: Put the conditional operator in parentheses This helps with reading, because it is easier to make out the scope of the operator: I prefer four spaces per level of indentation, because that makes the indentation more visible. The following metacide expressions are equivalent:
