What Is An Argument?

Table of contents


When you take a look at mathematical formulas most of them usually have alphabets say x or y in them, and the intention is that anyone using these formulas will replace the x and ys with actual values. In the programming world functions can be viewed as these formulas and arguments will be the values you pass in to replace x and y

Use Cases and Examples

Here is an example of a function in Javascript that adds two parameters [→] together:

01: // declaring the function 02: function adder(a, b) { 03: return a+b; 04: } 05: 06: // using the function 07: adder(1,2);

What you have above is a function called adder that takes two parameters and returns the sum of a and b. The last bit of the code [→] shows how you will use this function. You will refer to the values you pass in to replace the parameters as arguments.


Your output will always correspond to what you passed in as arguments to a function or method.
