Warm-Up An IP address is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. There are two versions of the Internet protocol, and thus two versions of addresses. One of them is the IPv4 address. IPv4

Warm-Up Given a positive integer n write a function that returns how many unique factors it has. If it only has two (n itself and 1) return "prime". example: factorCount(4); //returns 3 (1, 2, and 4 are factors of 4) factorCount(3); //returns "prime"

We left off last time with the realization that our word-finding algorithm was too slow for large inputs. We can improve its performance by minimizing the number of page turns required to find a word. Amazingly, using binary search we can reduce the runtime from O(n) to O(logN)

You are a treasure hunter and you have found a cave that you believe holds hidden treasure. Several miles down this cave, you run into a wall with the following inscription: "Banh mi pull skateboard ipsum lorem, kombucha scenester banjo. Franzen mlkshk consequat, PBR&B lever lever listicle irony pop-up

TDD TDD stands for Test Driven Development. It works like this, you decided what this section of your software does, and before you write the code for that section you write a set of tests to verify that it would work as you expect. So your writing what your program

Although there a lot of testing frameworks out there it's not actually that difficult to write your own and it's a great way to understand how to write better unit tests. Before we get into this make sure to complete the try and catch basics. https://coursework.vschool.io/unit-testing-javascript/

This section is to help you learn quickly what, why and how of Unit testing. What is unit testing? Unit testing is the practice of breaking your program into smaller pieces and inspect each piece with tests. Tests run when changes are made to the code in your projects. The

When running JavaScript errors can occur. These can be made by mistakes in programming, unexpected values in input and other errors. To handle these errors the JavaScript programming language has these tools. The try keyword allows us to test blocks of code try { //your code } The code within the try

Create a new server from scratch and make a new mongoose schema of any kind that includes at least 5 properties. Make a model from the schema (you'll use mongoose.model(...)), and use that model to create a new instance of your schema in the database. No need to worry

Given a string including parentheses, write a function that returns true if every opening parentheses has a closing parentheses. Example function balanceParentheses(str){ // Your code here } balanceParentheses("()()") // Output: true balanceParentheses("(())") // Output: true balanceParentheses("()))") // Output: false Also, every closing parentheses needs an opening partner before it. balanceParentheses(")()(") // Output: false balanceParentheses("())(") // Output:

write a function that takes an array of coins as it’s first argument, and a string representing a coin as it’s second argument. Options for the strings in the array, and the the string representing a coin are restricted to the strings: “penny", “nickel", “dime", “quarter", "half dollar"

Install Homebrew Homebrew is an excellent package manager for MacOS-specific programs. It essentially gives you a way to install certain programs (usually developer-y ones) directly from the command line. It's similar to how NPM or Bower works. To install Homebrew: * Head to the homebrew home page * Follow the instructions by

Using the following code: // readline-sync stuff here function add(a, b){ return a + b; } function subtract(a, b){ return a - b; } function multiply(a, b){ return a * b; } function divide(a, b){ return a / b; } function calculate(a, b, operationFunction){ //your code here. } Make a calculator that will take
