what are the core/basic functions in javascript
<p>Does javascript have a set of core functionality. If so where can I find it?</p>

<p>Java for instance has all the java.lang packages which implement basic language functionality like String. Where is the equivalent of such functions (like window.alert()) implemented in javascript? Is there a set of core/basic functions that are shipped with every javascript implementation? What are these functions? </p>

<p>Thank you</p>
