+
+<p>This chapter documents all of JavaScript's standard, built-in objects, including their methods and properties.</p>
+
+<div class="onlyinclude">
+<p>The term "global objects" (or standard built-in objects) here is not to be confused with the <strong>global object</strong>. Here, global objects refer to <strong>objects in the global scope</strong> (but only if ECMAScript 5 strict mode is not used; in that case it returns <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined">undefined</a>). The <strong>global object</strong> itself can be accessed using the {{jsxref("Operators/this", "this")}} operator in the global scope. In fact, the global scope <strong>consists of</strong> the properties of the global object, including inherited properties, if any.</p>
+
+<p>Other objects in the global scope are either <a href="/en-US/docs/Web/JavaScript/Guide/Working_with_Objects#Creating_new_objects">created by the user script</a> or provided by the host application. The host objects available in browser contexts are documented in the <a href="/en-US/docs/Web/API/Reference">API reference</a>. For more information about the distinction between the <a href="/en-US/docs/DOM/DOM_Reference">DOM</a> and core <a href="/en-US/docs/Web/JavaScript">JavaScript</a>, see <a href="/en-US/docs/Web/JavaScript/JavaScript_technologies_overview">JavaScript technologies overview</a>.</p>
