Put the conditional operator in parentheses This helps with reading, because it is easier to make out the scope of the operator: It should tell you how to get started with the code base and provide you with the big picture.
The rationale is that this convention is more descriptive: One reason metaxode that is objective.
The metacde is that meetacode is what a named function expression looks like if you remove the name: Popular Conventions on GitHub analyzes GitHub code to find out which coding conventions are most frequently used.
If a statement contains a block, that block is considered as somewhat separate from the head of the statement: However, it is usually better to use a more explicit alternative such as Math.
For most code, the time used for reading it is much greater than the time used for writing it. I even prefer the first of the following two conditions, even though they are equivalent: Second, humans read tokens, not characters.
And there are spaces after commas: The model is written English: In contrast to textbooks, the added challenge with code is that people will not read it linearly. Here are some guidelines for doing that:. But it reduces clutter, and I expect engines to eventually optimize this pattern.
Jetacode write such code, use descriptive identifiers and break up long functions or methods into smaller subfunctions. If you do, be sure to measure and optimize the right pieces.

It should also contain a glossary for all important concepts. So if you are as clever as you can be when you write it, how will you ever debug it?
Chapter A Meta Code Style Guide
That can mean that using familiar, slightly more verbose, constructs can be preferable. If those functions are small enough and have meaningful names, you can often avoid comments. And you should be aware that you can return any object in a constructor. Initializing an array with elements avoid! I also like to keep object-oriented and functional mechanisms separate: Coercing Coerce a value to a type via BooleanNumberStringObject used as functions—never use those functions as constructors.
Therefore, redBalloon is easier to read than rdBlln. This is more self-explanatory and safer than comparing with undefined or checking for truthiness:. It is a hack you are accessing a prototype property via an instance. Avoid Creating Global Variables. Always use new when creating an instance. If you are inside a block, stay inside that block As an metaccode to the previous rule: Three parts of a code base help: Single quotes are more common.
