JavaScript 中的函数声明被提升到了函数定义。你可以在函数声明之前使用该函数:

 
-
hoisted(); // "foo"
+
hoisted(); // logs "foo"
 
-function hoisted() {
-     console.log("foo");
-}
-
-/* equal to*/
-var hoisted; 
-
-hoisted = function() {
-  console.log("foo");
-}
-hoisted();
-// "foo" 
+function hoisted() {
+  console.log('foo');
+}
 

 
 

 
注意 :函数表达式{{jsxref("Operators/function", "function expressions")}} 不会被提升:

 

 
-
notHoisted(); // TypeError: notHoisted is not a function
-
-var notHoisted = function() {
-   console.log("bar");
-};

+
notHoisted(); // TypeError: notHoisted is not a function
+
+var notHoisted = function() {
+  console.log('bar');
+};
+
