Inform an API user if he did something stupid: To identify if the value undefined has actually been passed by your method, you can check the arguments object: Documenting APIs One of the hardest tasks of software development is documenting things.

Choose one style and keep that style — even if you find yourself disliking it at some point in the future. It is not necessary to compress getters and setters into a single method in order to create a fluid interface — it boils down to personal preference.

Passing data by reference is often used to keep memory overhead low, values passed by reference can be changed anywhere outside your API and affect state within. How could your API help the developer to reduce the noise of repeating method calls?

Functions that change the state internal values of an object are called commands, functions that retrieve values are called queries.

To provide fluency, you have to think about code streams — where are you coming from and where you are headed. While method chaining is a pretty generic thing that you can easily make your code do, handling arguments is not.

While tuning up the URI. If you simply return an internal object, any changes made to it outside of your API will be reflected on your internal data. Some voices on the internet suggest writing out each component of a chain in their separate lines to get proper line-numbers for errors in a stack trace: Another advantage to this method is that the same script can be included in multiple pages, and editing the script file will update the script in every page that uses the external script file.How do you write HTML in a JavaScript file?
