JavaScript: Exploring the basics - how to insert a function argument into an empty array

I am currently struggling with a question and unsure of what to do, so I am seeking help to solve the following challenge:

Begin by creating an empty array.
Next, create a function that takes in one argument.
Within this function, add the argument to the previously created array.
Lastly, call the function and pass in a value of any type.*

To define an empty Array you can use:

const emptyArray = []

A simple function with 1 argument would look like this:

function oneArgument(argument) {}

The task "Inside the function, add the argument to the array" is where I'm encountering difficulty. Can someone explain what this step entails?

Finally, it seems that completing the process involves simply assigning a value to oneArgument(someValue).

Any assistance on this matter would be greatly appreciated :)

Answer №1

To begin, we initialize an empty array to store values. Following this step, a function is created with a single argument named number. We then add the input number to our array and execute the function.

Utilizing arguments in functions enables us to create reusable functions. This allows us to use the same function across our application with different types of numbers. For instance, one file may require the input of number 500, while another file may necessitate a negative number. The key concept here is reusability. Regardless of the type of number passed, the function will consistently behave in the same manner whenever it is called, albeit with varying numbers or other values. An argument signifies that the function anticipates a value, and this value may differ each time the function is invoked.

I trust this explanation proves beneficial.

const numbers = [];

function updateNumbersList (number) {
  numbers.push(number)
} 

updateNumbersList(1)

console.log(numbers)
