Your Age on a Different Planet
ever wondered?
Brief Synopsis
- Takes in your Earth age in years and returns to you your current age were you living on a different Solar System planet

- html, css, javascript

- webpack, webpack-cli, Babel
- VS Code, Chrome DevTools
Description
- Takes in your age in years ("Earth years")
- Takes in your selection for which planet in the Solar System to which your age will be converted
- Can also tell you a prediction of how many additional years you would expect to live on selected planet
- If you have achieved an age beyond selected planet's predicted life expectancy, the difference will be shown.
To clarify: a Mercury year lasts 88 Earth days due to that planet's quick pace at completing a full revolution around the Sun. Thus one would expect one's Mercury age to be much greater than Earth age, since 88 fits just over four times into 365.

| (conversion used: 1 Mars year = 687 Earth days) | ||
| Describe: convertToJupiter() | ||
| Test | Input | Output |

| (conversion used: 1 Jupiter year = 11.8618 Earth years) | ||
| Describe: calcLifeExpectance() | ||
| Test | Input | Output |
| should return a number that is the mean life expectancy in Earth years worldwide | new Age(45) | newAge.lifeExpect = 73 Earth years |
| Test | Input | Output |
| should return a number that accurately adjusts Earth years life expectancy up by 7 years | new Age(45) | |
| to be applied to users who mark they are from a first world country NOT in the Americas | newAge.region = "first world" && newAge.region !== "Americas" | newAge.lifeExpect = 80 Earth years |
| Test | Input | Output |
| should return a number that accurately adjusts Earth years life expectancy down by 10 years | new Age(45) | |
| to be applied to users who mark they are from an African country | newAge.region = "Africa" | newAge.lifeExpect = 63 Earth years |
| Test | Input | Output |
| should return a number that accurately adjusts Earth years life expectancy up by 6 years | new Age(45) | |
| to be applied to users who mark they are from a country in North or South America | newAge.region = "Americas" | newAge.lifeExpect = 79 Earth years |
| Test | Input | Output |
| should return a number that accurately adjusts Earth years life expectancy up by 2 years when | new Age(45) | newAge.lifeExpect = 75 Earth years |
| when users mark sex = "female" | newAge.sex = "female" | |
| Describe: calcYearsLeft() | Input | Output |
| Test | new Age(45) | |
| should return a number in Mercury years that finds the difference between current Mercury years | newAge.calcLifeExpectance() | |
| age and Mercury years life expectancy (no sex or region data provided, thus EarthExpected = 73) | newAge.calcYearsLeft("mercury") | newAge.mercuryLeft = (116.18) |
| Test | new Age(45) | |
| should return a number in Venus years that is the difference between current Venus years | newAge.calcLifeExpectance() | |
| age and Venus years life expectancy (no sex or region data provided, thus EarthExpected = 73) | newAge.calcYearsLeft("venus") | newAge.venusLeft = (45.50) |
| Test | new Age(45) | |
| should return a number in Mars years that is the difference between current Mars years | newAge.calcLifeExpectance() | |
| age and Mars years life expectancy (no sex or region data provided, thus EarthExpected = 73) | newAge.calcYearsLeft("mars") | newAge.marsLeft = (14.87) |
| Test | new Age(45) | |
| should return a number in Jupiter years that is the difference between current Jupiter years age | newAge.calcLifeExpectance() | |
| and Jupiter years life expectancy (no sex or region data provided, thus EarthExpected = 73) | newAge.calcYearsLeft("jupiter") | newAge.jupiterLeft = (6.15) |
| Describe: roundToNearestHundredth() | ||
| Test | new Age(45) | |
| should return a number that has more than two digits after its dot rounded to the nearest | roundToNearestHundredth(41.96549) | 41.97 |
| hundredth. | ||
| Describe: outlasterCheck() | ||
| Test | new Age(100) | newAge.yearsBeyond = 2.28 |
| should take in a planet and assign this.yearsBeyond to the positive value of .{PLANET}Left, when | newAge.calcLifeExpectance() | 41.97 |
| .{PLANET}Left is less than zero | newAge.outlasterCheck("jupiter") | |
Installation Instructions to Setup This Project on Your Machine
- Copy the following link to your clipboard: https://github.com/sinkstyt/galaxy-age.git
- Open a Bash Terminal (some might call it a 'command line')
- In this terminal window, navigate to a directory into which you will clone this project (make a local copy from the GitHub remote copy)
- Within your git bash terminal type in
$ git clonewith one space between "clone" and pasted clipboard contents (https://github.com/sinkstyt/galaxy-age.git)
at Terminal promt
users/YOUR_USERNAME/ $ git clone https://github.com/sinkstyt/galaxy-age.git
- After the page has been cloned to your chosen directory, use
$ cd galaxy-ageto switch into its root folder. - Check to see that you have npm installed with the prompt
$ npm -v. As long as the first number in the version is 3 or greater, you should not anticipate any problems. If you are using OS X or greater and npm is not installed, use the command$ brew install node - Check node version with
