Really stupid mistakes.js

// 1.Take me nearly 1.5 hours to figure it out

function buildTotalPrice(ths, arrs) {
  var _arrs = []
  var l = ths.length - 1

  for (var i = 0; i < l; i++) {
    var _arr = 0

    for (var n = 0, m = arrs.lenth; n < m; n++) {
      var vs = arrs[n].costs

      _arr += parseFloat(vs[i])
    }
    _arrs.push(_arr)
  }

  return _arrs
}

// 2. Take me nearly 30 minutes to figure it out:
