jsPsych is a javascript library for running behavioral experiments in a web browser. It consists of a core library, which is used by all experiments that use jsPsych, and a set of plugins. Plugins define a trial type. Each different kind of task -- reading instructions, categorizing stimuli, answering a question, etc... -- in an experiment uses a different plugin. There are a set of plugins available to use, and there are instructions on how to create your own plugin as well. As more plugins are created, we hope that they will be added to the jsPsych library, so that other researchers can create experiments more efficiently.

The getting started page covers a basic example of how to use jsPsych. We recommend you start there.
