Q1. Create an array of numbers and take input from the user to add numbers to this array. Q2. Keep adding numbers to an array in Q1 until the user adds 0. Q3. Filter the numbers that are divisble by 10 from an array. Q4. Create an array of squares of a given number Q5. Use reduce to calculate the factorial of a given number from an array of first n natural numbers. (n being the numbers whose factorial needs to be calculated)

Extented version of question 5 in which no array is given before and only you have to enter a number, is here you can consider that as a reference: let a = Number.parseInt(prompt("Enter a Number:")); let arr = []; while(a!=0){ arr.push(a); a-- } const factorial = (x, y)=>{ return x * y; } let newArr = arr.reduce(factorial); console.log(newArr); 🙌

I made the q5 a little tougher: If an array contains the 0 in it so simply print factorial is 1. Else get the 0 out of it and then use the reduce function to calculate factorial. ❤ It was fun doing it.

if you are doing in node.js environment then user input code is - const a = require('readline').createInterface({ input: process.stdin, output: process.stdout }); let arr = []; function askQuestion(i) { if (i < 10) { a.question(`Enter your ${(i+1)}th number = `, num => { arr.push(num); askQuestion(i + 1); }); } else { a.close(); console.log(arr) } } askQuestion(0); /* If you add console.log(arr) after askQuestion(0), the array will not be printed because the question method of the readline interface is asynchronous. This means that the console.log(arr) line will be executed before all the questions have been asked and answered, and before the arr array has been fully populated. */
