Functions
Complete the following steps
- Using function declaration, define a function named add that takes two arguments, number1 and number2
- In the function, return the sum of the parameters number1 and number2
- Using function declaration, define another function named addNumbers that gets the values of two HTML form controls with IDs of addend1 and addend2. Pass them to the sum function
- Assign the return value to an HTML form element with an ID of sum
- Add a "click" event listener to the HTML button with an ID of addNumbers that calls the addNumbers function
- Using function expressions, repeat Steps 1-5 with new functions named subtract and subtractNumbers and HTML form controls with IDs of minuend, subtrahend, difference and subtractNumbers
- Using arrow functions, repeat Steps 1-5 with new functions named multiply and multiplyNumbers and HTML form controls with IDs of factor1, factor2, product and multiplyNumbers
- Using any of the three function declaration types, repeat Steps 1-5 with new functions named divide and divideNumbers and HTML form controls with IDs of dividend, divisor, quotient and divideNumbers
- Test all of the mathematical functionality of the task3.html page.
Built-In Methods
Complete the following steps
- Declare and instantiate a variable of type Date to hold the current date
- Declare a variable to hold the current year
- Using the variable declared in Step 1, call the built-in getFullYear() method/function and assign it to the variable declared in Step 2
- Assign the current year variable to an HTML form element with an ID of year
Array Methods
Complete the following steps
- Declare and instantiate an array variable to hold the numbers 1 through 25
- Assign the value of the array variable to the HTML element with an ID of array
- Use the filter() array method to find all of the odd numbers of the array variable and assign the reult to the HTML element with an ID of odds ( hint: % (modulus operartor) )
- Use the filter() array method to find all of the even numbers of the array variable and assign the result to the HTML element with an ID of evens
- Use the reduce() array method to sum the array variable elements and assign the result to the HTML element with an ID of sumOfArray
- Use the map() array method to multiple each element in the array variable by 2 and assign the result to the HTML element with an ID of multiplied
- Use the map() and reduce() array methods to sum the array elements after multiplying each element by two. Assign the result to the HTML element with an ID of sumOfMultiplied
