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

[RobMack8932]

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

// Name and coffee amount

const fullName = 'Rob Mack' const numberOfCupsOfCoffee = 2 console.log( Hey my name is ${fullName} and I drink ${numberOfCupsOfCoffee} cups of coffee a day! ) // User name const userName = window.prompt('What is your name?') console.log(Hey there ${userName}) // Input Numbers const firstOperand = window.prompt('Give me a number any number!') console.log(Okay, ${firstOperand} it is!) parseFloat(firstOperand) const secondOperand = window.prompt('I lied, one more..!') console.log(Okay, ${secondOperand} it is!) parseFloat(secondOperand) //Math const sum = +firstOperand + +secondOperand console.log( If you add ${firstOperand} and ${secondOperand} you will get ${sum} ) //subtract const difference = firstOperand - secondOperand console.log( If you subtract ${firstOperand} by ${secondOperand} you will get ${difference} ) //multiply const product = firstOperand * secondOperand console.log( If you multiply ${firstOperand} and ${secondOperand} you will get ${product} ) //divide const quotient = firstOperand / secondOperand console.log( If you divide ${firstOperand} by ${secondOperand} you will get ${quotient} ) //arrays

const numbers = [ 61, 41, 65, 21, 44, 98, 20, 32, 54, 49, 84, 74, 16, 59, 5, 12, 44, 31, 52, 78, 66, 10, 48, 17, 33, 39, 20, 9, 61, 66, 56, 36, 25, 75, 69, 77, 2, 7, 87, 63, 15, 66, 37, 81, 33, 74, 71, 52, 89, 58, 27, 93, 80, 95, 16, 50, 72, 18, 77, 88, 34, 20, 56, 18, 66, 43, 34, 31, 11, 77, 8, 31, 100, 12, 83, 96, 21, 31, 17, 24, 77, 78, 70, 85, 7, 59, 5, 12, 76, 5, 21, 73, 3, 38, 28, 70, 68, 90, 34, 42, ] const smallest = numbers[0] console.log(smallest)

Hey Gavin I couldn't git push this one so I just wanted to copy and paste it, been stumped on the arrays for awhile so

Your homework 06 - 01 - console.log('Welcome to JavaScript') was marked: Acceptable

“Hmm ok ”

[gstark]

See if you can work with Jordan and get this in a repository and work on the array part. I'm going to mark this as acceptable, but I think it is a good assignment to revisit later.
