JavaScript - Prompt Loop and Storing Input The next element of the program is to continue to prompt the user for input, storing each input into an array, until the user does not enter anything into the prompt dialog. First, you'll need an empty array.
Part 4: JavaScript - Prompt Loop and Storing Input
The next element of the program is to continue to prompt the user for input, storing each input into an array, until the user does not enter anything into the prompt dialog. First, you'll need an empty array.
>> Add an empty array to the startup function. Name the array data. Declare the array as a constant array.
Tip: Making our array a constant array prevents us from accidentally overwriting the entire array contents, but does not prevent us from adding data to the array.
With the input storage ready, we can know work on our prompt loop. You will need to figure out how to continuously prompt the user for input using the prompt function, and either a while loop, or a do...while loop - either loop structure will work. You can ignore storing the input for now, and just focus on the prompt loop.
>> Add code to the startup function to continuously prompt the user for input using either while or do...while, and the prompt function, until the user leaves the prompt input dialog empty.
Tip: You will need to use String functionality to test if the input is empty or not.
Once you have the prompt loop complete, you can modify the loop to capture the input by adding each input into the data array.
>> Add code to the prompt loop that adds the input into the array. You will need to use an array function that adds array elements to the end of the array. After each input is added to the array, the array will be one element in length larger.
Tip: The assignment will require all input to be converted to upper case letters, and to be displayed in a random color. You may be tempted to modify the input data as the data is added to the array, but leave the data as entered by the user.
