why we need to use arguments inside a function ?

Question

I finished learning Jequery I practiced all the things I learnt but I still a little bit confused about arguments, I want to know exactly what is the importance of using arguments in a function , for example if I want to use preventDefault(); on an element is it obligatory to use event ? or there is an other way to use the preventDefault function without passing any argument through the function ?

Answer 2

Arguments are actual parameters that are passed to the calling method/function usually resulting in somthing being returned
