JavaScript 1 Extra Practice With Test Suites

Instructions

• You do NOT need to check out to another branch you can work off the main branch.

• Write all your code in solutions.js

Problems

1. Create a function named sum that returns the sum of two numbers.

    sum(2, 3)  // Output: 5
    sum(7, -59);  // Output: -52
    sum() // Output: false
    sum("2", 2) // Output : false
    sum(false, 3) // Output: false
    sum(2, []) // Output: false
    sum({}, 7) // Output: false
   

2. Create a function named reverseString that returns the reverse of a given string.

     reverseString("hello");  // Output: "olleh"
     reverseString("Grace Hopper");  // Output: "reppoH ecarG"
     reverseString(); // Output: false
     reverseString(2) // Output: false
     reverseString([]) // Output: false
     reverseString({}) // Output: false
   

3. Create a function named findLargestNumber that returns the largest number from an array of numbers.

    findLargestNumber([4, 9, 2, 7, 5]);  // Output: 9
    findLargestNumber([1, 2, 3, 4, 5]);  // Output: 5
    findLargestNumber() // Output: false
    findLargestNumber("A string) // Output: false
    findLargestNumber(["a", "string"]) // Output: false
   

4. Create a function named checkEvenOrOdd that checks if a number is even or odd.

    checkEvenOrOdd(2) // Output: "Even"
    checkEvenOrOdd(7) // Output: "Odd"
    checkEvenOrOdd("") // Output: false
    checkEvenOrOdd([]) // Output: false
   

5. Create a function named convertToFahrenheit that converts a temperature from Celsius to Fahrenheit.

    convertToFahrenheit("") // Output: false
    convertToFahrenheit(20) // Output: 68
    convertToFahrenheit(-10) // Output: 14
    convertToFahrenheit([1,2,3]) // Output: false
