It can be used to invoke (call) a method with an object as an argument (parameter). Note Withcall(), an object can use a method belonging to another object. This example calls thefullNamemethod of person, using it onperson1:
Description TheMath.max()method returns the number with the highest value. See Also: The Math.min() Method Syntax Math.max(n1,n2,...) Parameters ParameterDescription n1, n2,...Optional. One or more numbers to compare. Return Value
Now, for convenience, let’s create a reference to thewhoAmImethod, presumably so we can access it merely bywhoAmI()rather than the longerobj.whoAmI(): varwhoAmI = obj.whoAmI; And just to be sure we’ve stored a reference to a function, let’s print out the value of our newwhoAmIvar...
Next, let's see what happens if you specify a length parameter with the endsWith() method. For example: var totn_string = 'TechOnTheNet'; console.log(totn_string.endsWith('On',6)); The following will be output to the web browser console log: true In this example, we have set ...

(undefinedis a value assigned to formal arguments which there are no actual arguments,so you might expect thatNumberwithout arguments takesundefinedas a value of its parameter)然而当我们传一个undefined的时候,我们将得到NaN。 代码语言:javascript
Now it works as expected. With the(function(index) {...})(i)approach, a new function is created - along with a new scope - for each iteration and the new function will hold the proper value ofiin the function parameterindex. (Note: I usedindexin order to make the example easy to ...
