We are going to write a function called filter_list that will accept an array, l, as an argument.

You are given an array of integers and strings. The goal of the function is to return a new array of the same elements but without the strings.

Example:

filter_list([1,2,'a','b']) 
//output: [1,2]filter_list([1,'a','b',0,15]) 
// output: [1,0,15]

This function is pretty short so first we start by using the filter method to filter out the strings from the input array. To check if an element is a string or a number, we use the typeof operator. …

We are going to write a function called reverseWords that accepts a string, str, as an argument.

You are given a string of varying word counts. The goal of the function is to reverse every word in the string and return it.

Example:

reverseWords('The quick brown fox jumps over the lazy dog.')
// output: 'ehT kciuq nworb xof spmuj revo eht yzal .god'

The first thing we are going to do is create a variable called reverseWordArr. This variable will contain our string in array form.

let reverseWordArr = str.split(" ")

Since we want to create another array but containing…

We are going to write a function called squareSum, that accepts an array of integers, numbers, an argument.

You are given an array of positive and/or negative numbers. The goal of the function is to square each number in the array and sum the results of the squares together. The function returns that sum.

Example:

squareSum([0, 3, 4, 5]) //output: 50

If we squared each number and add them together,

0^2 + 3^2 + 4^2 + 5^2 = 0 + 9 + 16 + 25 = 50

we get a total of 50.

Let’s begin.

First, we create a variable…

We are going to write a function called, invert, that will accept an array of numbers, array, as an argument.

You are given an array containing both positive and negative values. The goal of the function is to return the inverse of each of the numbers. In other words, make all negative values positive and make all positive values negative.

Example:

invert([-17,-6,-15,0,-20,-77,-47])
// output: [17, 6, 15, -0, 20, 77, 47]

From the example above you will see that all the negative values are positive and all the negative values are positive in the output array. Also in the output…

We are going to write a function called past that will accept three integers, h, m, s, as an integer.

There is a clock that shows the time in hours h, minutes m, and seconds s. The hours, minutes, and seconds shows the time since midnight. The goal of the function is to return the time in milliseconds.

Example:

past(1,1,1) // output: 3661000

In the example above the clock shows 1 hour, 1 minute, and 1 second had passed since midnight.

To convert the time from seconds to milliseconds, you multiply:

seconds x 1000

To convert the time from minutes…

Once upon a time, there was a male chicken named Dick. Dick had other friends who were also Dicks.

Once upon a time, there was a candle that smelled like Canadian bacon. No one knew why it smelled that way.

The candle was advertised to smell like mint and cinnamon but it smelled like bacon.

People that bought it returned it but no store could accept it. It smelled too pungent. The longer it burned the stronger the bacon smell. Next thing the smell started getting into the walls. When the candle burned out, the entire house continued to smell like Canadian bacon for 40 days.

You could smell the candle from outside the house. It smelled like a…
