Loops II - Activity

Loops

Make sure you attempt the activity on your own before checking out the solution.

Instructions

Create a flowchart to represent the following program, then code it out.

  1. Using a loop, prompt the user to enter five names.
  2. Push each name to a nameList array.
  3. Using another loop, render/alert the five student names.

Challenge:

Don't forget to flowchart FIRST!

  1. Prompt the user for a number of students in the class.
  2. Prompt the user to input that many names.
  3. Render all of the names.

Ultra Challenge:

Working off of the bonus, print only the people whose names include the letter a.

Solution 
const nameList = [];

for (let i = 0; i < 5; i++){
  const name = prompt('Enter a name');
  nameList.push(name);
}

for (let i = 0; i < nameList.length; i++){
  const name = nameList[i];
  alert(name);
}

// Challenge

const challengeList = [];
const challengeQuestion = parseInt(prompt('How many people are in the class?'));

for (let i = 0; i < challengeQuestion; i++) {
    const newName = prompt(`Enter person number ${i+1}'s name:`);
    challengeList.push(newName);
}

for (let i = 0; i < challengeList.length; i++) {
    console.log(challengeList[i]);
}

// ULTRA CHALLENGE

for (let i = 0; i < challengeList.length; i++) {
    if (challengeList[i].includes('a')) {
        console.log(challengeList[i]);
    }
}
