// In the original code, a new object is created on every iteration with the spread
// operator (...). This can be inefficient if the number of iterations is large.
// By creating the newAttributes object before the loop and then updating it inside the loop,
//  you only create a single object, which can be more efficient.
//
// The original code also uses the Object.keys() function to get an array of the keys in
//  entity.attributes.templates, and then uses the forEach() function to iterate over the
//  array. This is an additional step that can add some overhead. In the optimized code,
//  the for loop is used instead, which can be a more efficient way to iterate over an array.
//
// The optimized code also uses the optional chaining operator (?.[]) to access properties
// of entity.untemplated_attributes, which can be more concise and readable than the
// original code.
//
// Overall, these changes can make the maybeApplyTemplateAttributes() function more
// efficient, particularly if it is called frequently or if entity.attributes.templates
// has a large number of keys.


// This revised version of the updateMoreInfo function does not use requestAnimationFrame at
// all.(.....) Instead, it selects all the necessary elements directly in a single call to
// querySelectorAll. This can potentially be faster and more efficient than making multiple
// querySelector calls and using getElementsByClassName, because it only requires the DOM to
// be traversed once.
//

// By wrapping the function in a requestAnimationFrame call, you can ensure that the browser
// is able to optimize the rendering of the page and minimize the impact of the function on
// the main thread. This can help improve the performance of the code and provide a smoother
// user experience. However, if the updateMoreInfo function is not modifying the DOM, then
// there may not be a need to use requestAnimationFrame. It would be up to you to determine
// whether using requestAnimationFrame is necessary in this case.


// Additionally, by eliminating the checkElements function and the use of
// requestAnimationFrame, the revised version of the code is simpler and easier to read. r
// equestAnimationFrame is a way to execute a function just before the browser is about to
// repaint the page, and it is generally used to improve performance by allowing the browser
// to handle DOM manipulation in an optimal way. However, in this case, the checkElements
// function was being used to repeatedly check for the existence of certain DOM elements,
// which is not the intended use of requestAnimationFrame. By selecting all the necessary
// elements in a single call, the revised version of the code avoids the need to use
// requestAnimationFrame for this purpose.

// By storing the selected DOM elements in variables outside of the updateMoreInfo function,
// they will only be selected once and then be referenced from the cached variables in
// subsequent calls to the function, which should improve the performance of the code.
//
// Avoid using .innerText to get the text of an element. Instead, use .textContent as it is
// faster.

// Instead of using Array.from(attributesEl.querySelectorAll(".data-entry")), you can
// use [...attributesEl.querySelectorAll(".data-entry")] to create an array.
// This is faster and more concise.

// using the spread operator (...) is faster than Array.from() when creating an array from a
// DOM collection. This is because Array.from() has to call the Array() constructor and has
// to perform additional checks and operations, whereas the spread operator simply creates
// a new array with the same elements as the original DOM collection
