what is going on guys my name is Michael and welcome to your third required Shias tutorial in which well be covering about the required keyword well I said that I would cover the configuration file in this tutorial but I guess I missed this one so yeah so before doing the configuration file lets just quickly hop over to what this require keyword is so as I told you that data mean accepts the configuration file of your application and for now it is just a config dot Js which is a blank file and yeah so after this script loads itself that is this require – one two – then it would load this one and since they are in the same part so I dont need to just add GS or something like that and the next thing Im doing is Im using the
require again so what required does is it would load a file as just like you are adding a file out of script SRC so this technically means that this bunch of code here means that we are doing something like this only but youll say that hey we already did that in the slides so what is the use of this code right here so Ill just show you that in a minute so right here what I told you is that this script file would load itself first and then this config dot GS right here which does not require a dot Js extension so you can just make use of this as config and not config dot Js so what happens here is that this is an asynchronous call so when this required – one – two loads this asynchronously calls this config file
wont work because this is odd I told you is asynchronously loading this file so the code below this script might or might not run at times see you might not take any chances now what about that with this if I write a lot in here and then I reload then as you can see this conflict not gist is already present so if I can show both of these together hello it before require keyword and alert after require keyword and if I reload this now as you can see the before require keyword fires before the config dot JS file is loaded and this after require keyword is immediately fired after this conflict GS is loaded so this is kind of a callback function you can see which will be fired when this file is loaded and dont worry about duplicates require GS will
