I am doing recommend system function but i meet a problem like below

const getProductRecommmend = asyncHandler(async (req, res) => {
  let arrMeasure = []
  
  const comparePromise = (desc) => {
    return new Promise((resolve,rejects) => {
      tfidf.tfidfs(desc,function (i,measure) {
        arrMeasure.push({
          index:i,
          measureProps:measure
        })
      })
      resolve(arrMeasure)
    })
  }



  const lastOrder = await (await Order.find({ user: req.user._id })).pop()
  const products = await Product.find({})
  // console.log(products)
  products.forEach(item => {
    tfidf.addDocument(item.description);
  })
  let arrResultMeasure = []
  
  lastOrder.orderItems.forEach(async(item) => {
    const product = await Product.findById(item.product).select('description')
    const resultMeasure = await comparePromise(product.description)  
    arrResultMeasure = [...resultMeasure]
    // console.log('arrResultMeasure',arrResultMeasure)
  })
  console.log('arr1',arrResultMeasure) // empty array
  res.json(lastOrder) 
})

When I console log arrResultMeasure inside forEach, it still log value, but when I console log outside of it, as you see in this below code, it return an empty array, I tried many way but it's still doesn't work.Does anyone have a solution to this problem? Thank you!
