> Let's suppose you have your program folder as my_program then create a js folder in this directory and paste the jquery file you had copied in it (my_program/js/jquery.js).
> JQuery comes with different versions i.e jquery-3.1.1.min.js just copy the whole file and paste it in your js folder.
> The my_program directory need not to be in a specific directory, you can just create it anywhere.
> Unless you are to use PHP as it will apply in our case hence be in this directory; C:/xampp/htdocs/my_program/js/jquery.js as your file directory.
Install jquery from an existing CDN
> You can also install jquery from an existing CDN like Google, Microsoft CDNJS or jsDelivr.
> This is the best method, since it allows faster loading especially if you are moving from another website into yours it makes it easy to supply the jquery script into yours from a cahe of the previous website.
> Once the file is requested, it will be provided by the nearest server.
> To implement this, just paste below line of code between your head tags <head>...</head> in the file where you want to use jQuery like index.html
> To this point you have JQuery installed and now our next task is to check if it is working.
> Let’s use Jquery to give an alert box saying okay when a page finishes loading.
