window.array = [1, 4, 3, 4, 2, 2, 1, 5, 3, 5, 1, 4, 3, 4, 2, 2, 1, 5, 3, 5, 1, 4, 3, 4, 2, 2, 1, 5, 3, 5, 1, 4, 3, 4, 2, 2, 1, 5, 3, 5, 1, 4, 3, 4, 2, 2, 1, 5, 3, 5];
Tests:

  • Filter length

     
    const x = _.filter(window.array, i => i === 3).length;
    return x;

  • Sum

     
    const x = _.sumBy(window.array, i => i === 3 ? 1 : 0);
    return x;

  • Manual

     
    let x = 0;
    let array = window.array;
    let len = array.length;
    for (let i = 0; i < len; i++) {
      if (array[i] === 3) {
        x++;
      }
    }
    return x;
