    # Lab 1, Part 4 — Stretch Goal: Project Euler

    ## Introduction

    Practice your Javascript and math skills by solving a problem on Project
    Euler. Project Euler is a series of challenging math and computer science
    problems that can be solved using any language (for our class, use
    Javascript).

    Solve the first problem on this page https://projecteuler.net/archives
    (Multiples of 3 and 5). To check your answer, create an account and you will
    be able to submit your final result.

    If you complete problem 1, move on to problem 2!

    /* =====================

    Start code

    ===================== */
    let sum = 0;
    for(let i = 1; i < 1000; i++) {
      if(i%3===0 | i%5===0) {sum = sum + i;};
    }
    console.log('Sum = ' + sum)

    let sum2 = 0;
    let j = [1, 1];
    for(let i=1; i < 4000000; i = j[0] + j[1]) {
      if(i%2===0) {sum2 = sum2 + i};
      j[0] = j[1];
      j[1] = i;
      //console.log("i " + i + ' j ' +j);

    }
    console.log('Sum2 = ' + sum2)

    /* =====================

    End code
