Best Practices
Regardless of the project type, there are several best practices that apply to JavaScript file and directory structure:
- One object per file
-
Each JavaScript file should contain code for just one JavaScript object. This pattern is common to other programming languages and generally makes maintenance easier. Having multiple files with single objects reduces the risk of multiple people working on the same file at the same time. Even though today’s source control systems are incredibly good at merging changes from two different people, merge conflicts do still occur. The fewer files you have, the greater the likelihood of merge conflicts. Keeping one JavaScript object per file minimizes this risk.
