Use lookaheads in the pwRegex to match passwords that are greater than 5 characters long and have two consecutive digits.
let sampleWord = "astronaut";

// Your regex should use two positive lookaheads.

You need to check all the usernames in a database. Here are some simple rules that users have to follow when creating their username. 1) The only numbers in the username have to be at the end. There can be zero or more of them at the end. 2) Username letters can be lowercase and uppercase. 3) Usernames have to be at least two characters long. A …
let username = "JackOfAllTrades";

nickihastings / pairwise.js
Created April 17, 2018 19:01
Given an array arr, find element pairs whose sum equal the second argument arg and return the sum of their indices. If multiple pairs are possible that have the same numeric elements but different indices, return the smallest sum of indices. Once an element has been used, it cannot be reused to pair with another. For example pairwise([7, 9, 11, …
function pairwise(arr, arg) {
//if its an empty array return 0
if(arr.length === 0){
return 0;
}
//reduce the array by looping over the array and checking if the
//sum of the current element and another element = the argument.
//if they match and the indexes of both are different, add the indexes to
//the output array.
var pairs = arr.reduce(function(accum, curr, index, array){

Return a new array that transforms the element's average altitude into their orbital periods. The array will contain objects in the format {name: 'name', avgAlt: avgAlt}. You can read about orbital periods on wikipedia. The values should be rounded to the nearest whole number. The body being orbited is Earth. The radius of the earth is 6367.4447…
function orbitalPeriod(arr) {
var GM = 398600.4418;
var earthRadius = 6367.4447;
//create a function to calculate orbital period
function calcPeriod(avgAlt){
var orbitalRadius = earthRadius + avgAlt;
//calculation is 2 multiplied by pi multiplied by the square root of the
//orbital radius to the power of 3 divided by the GM
var period = Math.round(2*Math.PI*(Math.sqrt(Math.pow(orbitalRadius,3)/GM)));
return period;
