These 5 projects are required to complete the JavaScript certificate on SoloLearn.
The function planTrip() takes in a distance, and returns the estimated time off arrival. I utilize default parameters, guard clauses, and ES6 to complete.
From SoloLearn:
You need to plan a road trip. You are traveling at an average speed of 40 miles an hour. Given a distance in miles as input (the code to take input is already present), output to the console the time it will take you to cover it in minutes.
Sample Input: 150
Sample Output: 225
Explanation: It will take 150/40 = 3.75 hours to cover the distance, which is equivalent to 3.75*60 = 225 minutes.
The function snailInTheWell() will wrap my other functions. These are called in a specific recursive order, so that if the snail escapes before nightfall, the function call will cease. I utilized while loops, default parameters, guard clauses, conditional statements, and the const variable to complete.
From SoloLearn:
The snail climbs up 7 feet each day and slips back 2 feet each night. How many days will it take the snail to get out of a well with the given depth?
Sample Input: 31
Sample Output: 6
Explanation: Let's break down the distance the snail covers each day: Day 1: 7-2=5 Day 2: 5+7-2=10 Day 3: 10+7-2=15 Day 4: 15+7-2=20 Day 5: 20+7-2=25 Day 6: 25+7=32 So, on Day 6 the snail will reach 32 feet and get out of the well at day, without slipping back that night.
Hint: You can use a loop to calculate the distance the snail covers each day, and break the loop when it reaches the desired distance.
This project required that I write a function to take in an amount to convert and the exchange rate. It should return the product of those two inputs.
From SoloLearn:
You are making a currency converter app. Create a function called convert, which takes two parameters: the amount to convert, and the rate, and returns the resulting amount. The code to take the parameters as input and call the function is already present in the Playground. Create the function to make the code work.
Sample Input: 100 1.1
Sample Output: 110
Converting 100 at the rate of 1.1 is equal to 100*1.1 = 110.
The goal of the funciton contact() is to take in a name an number input, and output them in this format: ${this.name}: ${this.number}. I utilize default values, template literals, custom methods, and ES6.
From SoloLearn:
You are working on a Contact Manager app. You have created the contact object constructor, which has two arguments, name and number. You need to add a print() method to the object, which will output the contact data to the console in the following format: name: number The given code declares two objects and calls their print() methods. Complete the code by defining the print() method for the objects.
The goal of this function is to recursively mutate an array of numbers, based on an input. Currently is themed around a store's prices, and appyling a given increase. For this project, I utilized default values, arrow functions, higher-order funcitons and ES6.
From SoloLearn:
You are working on a Store Manager program, which stores the prices in an array. You need to add functionality to increase the prices by the given amount. The increase variable is taken from user input. You need to increase all the prices in the given array by that amount and output to the console the resulting array. Use a loop to iterate through the array and increase all items.
The goal of this script is to concatenate any words given with a dollar sign in front and back of it. This is often formatting used for encryptions. Techniques I utilize here: class constructors, method creation, and other ES6 features like the spread operator.
From SoloLearn:
You are making a text encryptor. It should take multiple words and output a combined version, where each word is separated by a dollar sign $. For example, for the words "hello", "how", "are", "you", the output should be "$hello$how$are$you$". The given code declares a class named Add, with a constructor that takes one rest parameter. Complete the code by adding a print() method to the class, which should generate the requested output. Note, that the dollar sign is placed at the beginning and at the end of the output.
