06 - 01 - console.log('Welcome to JavaScript')

Let's get started

Today, we are starting our journey into JavaScript. For this assignment, you will be making a program that demonstrates some JavaScript fundamentals.

Objectives

• Ensure your development environment is setup
• Practice creating variables
• Practice working with user input

Requirements

Create your project using app-app with the beta stack

Remove all the code inside main.js and start with a fresh and empty file.

Explorer Mode

• [ ] Create a new app that does the following.

  • Practice Creating Variables

  • Create a variable that stores the numberOfCupsOfCoffee that you drink every day (even if that is zero).

  • Create a variable called fullName and set it equal to your full name.

  • Use console.log and your variables, numberOfCupsOfCoffee and fullName to output all three on one line.

  • Practice Getting Input From the User

  • Ask the user for their name and store it in a variable named userName. (use window.prompt to get input from the user)

  • Console log a greeting to the user, using their name.

  • Converting String Input Into Numbers

  • Input two numbers from the user. Use window.prompt twice, once for each prompt/number. Convert each resulting string from window.prompt to a float using parseFloat. Save the first value in a variable named firstOperand and the second value in a variable named secondOperand.

  • Doing Math

  • Add the operand variables from above and save the results in a variable named sum.

  • Subtract the secondOperand variable from the firstOperand variable and save the results in a variable named difference.

  • Multiply the operand variables and save the results in a variable named product.

  • Divide the firstOperand by the secondOperand and save the results in a variable named quotient.

  • Find the remainder when one operand is divided by the other and save the results in a variable named remainder.

  • Use console.log to present the user, in a meaningful way, each of the values for the sum, difference, quotient, product, and remainder variables. (e.g. perhaps one of your outputs is similar to If you add 4 and 5 you get 9 if 4 and 5 were the input)

  • Using Arrays

  • Use this page to generate a array of random numbers.

  • Place these numbers into a properly formatted array named numbers.

  • Determine the following. Use JavaScripts for loops to your advantage.

    • In a variable named smallest, find the smallest value in the array
    • In a variable named largest, find the largest value in the array
    • In a variable named sum, find the sum of all the values in the array
    • In a variable named average, find the average of all the values in the array

Adventure Mode

• Revisit your arrays. This time create new variables that represent:
  • sumOfOdd that contains the sum of all the odd numbers
  • countOfEven that contains the total count of all the even numbers

I tried to follow your code and lecture slides on line spacing, but please let me know if I did any mistakes if you can. Thank you! :)

Code logic and spacing looks good.

Try to avoid i as variables: https://github.com/AbtaheeAli/first-java-script/blob/master/public/main.js#L154
