How good are you really.js

// There was a test in your class and you passed it. Congratulations!
// But you're an ambitious person. You want to know if you're better than the average student in your class.

// You receive an array with your peers' test scores. Now calculate the average and compare your score!

// Return True if you're better, else False!

// Note:
// Your points are not included in the array of your class's points. For calculating the average point you may add your point to the given array!

///////////// Solution //////////////

function betterThanAverage(classPoints, yourPoints) {
    // Your code here 
    return (classPoints.reduce((a,b) => a + b) / classPoints.length) < yourPoints
  }
