根据结果用javascript更改p的背景色

我需要在p标记中更改结果的背景色,如果变量的结果为>则为1。 我想这可以通过一个if语句来完成吗? 这是我正在处理的代码:

const todos = [{
  text: 'Order airline tickets',
  completed: false
},{
  text: 'Vaccine appointment',
  completed: true
}, {
  text: 'Order Visa',
  completed: true
}, {
  text: 'Book hotell',
  completed: false
}, {
  text: 'Book taxi to airport',
  completed: true
}]

const filters = {
  searchText: ''
}

const renderTodos = function (todos, filters) {

  //use filter method for the title search string and save it to filters variable
    const filteredTodos = todos.filter(function (todo) {
        return todo.text.toLowerCase().includes(filters.searchText.toLowerCase())
    })

    const notDone = filteredTodos.filter(function (todo) {
      return !todo.completed
    })

    //Empty the div containg the result, this has to be between filter and the display of the result
    document.querySelector('#todos').innerHTML = ''

    const summary = document.createElement('h4')
    summary.textContent = `You found ${notDone.length} hits on this search that are not complete`
    document.querySelector('#todos').appendChild(summary)



    //loop through note object, create a p tag for the title searched and append to the div
    filteredTodos.forEach(function (todo) {
        const noteEl = document.createElement('p')
        noteEl.textContent = todo.text
        document.querySelector('#todos').appendChild(noteEl)

    })
    elem = document.createElement("hr")
    document.querySelector('#todos').appendChild(elem)
}

document.querySelector('#search-todo').addEventListener('input', function (e) {
  filters.searchText = e.target.value
  renderTodos(todos, filters)
})

所以搜索的结果,如果还有!todo.completed在我要附加到todos div的p标记中,只有那些p标记的p背景色应该是黄色。

谢谢
