What are aliases and arguments in Custom Commands?

Aliases

Aliases are alternative name for a command. For example you made a command named test and you want it to be ran by other names such as testing or tester then you dont have to make 3 different commands. You just make one command named test and add the 2 other name as aliases. This way the command can be ran using those 3 names and it will give the same response

Arguments

Arguments are parameters required to run a command. For example if you made a command named hello and you want it to pass the name of the person to say hello then you will add an argument and use that in command content or embed. See the example below.
