Показать описание

It is similar to the 'apply' method in that it allows you to specify the value for 'this' however you pass in arguments separated by comma using the call method.

In this video I take you through a simple example of the call method, showing you exactly what it does and being as simple as possible.

I'm even more confused now. What's call() good for? When would I need it?

I was reading the mozilla docs on this and I didn't understand it, now I get it :)
You're explaining really well!!

Very simple explanation. It would be good to see an example with better context, like a more real life situation when I need to use .call()

As we regular function like function name(){ }
then what is the use of using call() method with regular function, I think we can do the same, would you tell me something extra to clear my confusion that when we need to use call method in function as you have used in the video, , , , plz?

If you're calling a specific function and changing the value of the "this" keyword then the question remains as to what purpose the call was made to that function.

It doesn't work for me when I use ('${first} ${last}');

Is this the same if you code in the developer console

If you are talking to genuine CODE DEVELOPERS perhaps this makes all perfect sense. BUT, to someone like me you dont and the reason is you have jumped right into the code without explaining or showing what you are trying to do in the first place. SHOW US the BEFORE AND AFTER WEBSITE and then show us the code so it can make better sense please. The code is does not seem difficult but really explains nothing to me.
