The W3C Performance Timeline API is a specification that defines performance timeline primitives that are necessary for web developers to access, instrument, and retrieve a variety of performance metrics from a web application across its full lifecycle. This specification is a draft document that should be cited only as a work in progress.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
