    Introduction

    The Dojo framework is a javascript library that Wave Maker is built on top of. In addition to providing a set of libraries useful for building applications, it also provides sets of widgets. WaveMaker tries to take the best of dojo’s widgets and where we weren’t satisfied with what dojo had to offer, we provided some of our own widgets as well. WaveMaker is built using the dojo javascript toolkit all classes are declared using dojo’s object oriented class management system and in this sense, WaveMaker and any project built with wavemaker is
    built using the dojo toolkit.
