In programming, web designers use "argument" to mean any value which is used to pass to a section of a program that is needed to carry out a particular task. The section of such a program is known as a ROUTINE. For instance, given that the SQRT is a routine that returns the square root of a value, therefore, SQRT(81) would return the value '9'. In this case, the argument is denoted by 81.
It helps to serve several functions and can be used inorder to have conditional application of a command on the website. Web designers have to be very careful while they have arguments included on the website as they have to be very precise or else the user will get a different set of information that what is required. This is adversely affect the credibility of the website. Web designers hence have to be very careful with the aplication of arguments on the website.
Another definition web developers use to qualify argument is when it is substituted for "parameter"~ a word which could be used to mean a value which is not constant and can be changed easily. In other instances, web designers may want to differentiate between these two terms when they make use of "programming languages" which help to shed more ways of differentiating the two synonyms but yet distinctive words. In terms of programming languages , a parameter is one who is only passed in one direction while a parameter, on the other hand, is often passed back and forth. Even though this distinction is not yet popular, i think it makes a whole lot of sense!
Finally, an argument can mean an option to pass a command or an instruction from the web designer or a programmer to the computer. In this context, it is called "command-line argument".
