网页开发人员需要知道如何设计网页的尺寸.因此,给定一个特定的矩形网页s区域,你的工作现在是设计一个矩形网页,其长度L和宽度W满足以下要求:你设计的矩形网页的面积必须等于给定目标区域.宽度W不应该大于长度L,这意味着L >=W.长度L和宽度W之间的差距应该尽可能小.返回一个数组[L,W]其中L和W是你设计的网页的长度和宽度.
To design a rectangular web page with the given requirements, follow these steps:
1. Calculate the square root of the target area.
2. Round up the square root to the nearest integer, which will be the length L.
3. Calculate the width W by dividing the target area by the length L.
4. Round up the width W to the nearest integer if it is not already an integer.
5. Return the array [L, W].

Here is the function that implements these steps:

```
function designWebPage(targetArea) {
  const L = Math.ceil(Math.sqrt(targetArea));
  const W = Math.ceil(targetArea / L);
  return [L, W];
}
```

You can call the function with the target area as an argument, like this:

```
const targetArea = 24;
const [L, W] = designWebPage(targetArea);
console.log(`Length: ${L}, Width: ${W}`);
```

This will output:

```
Length: 5, Width: 5
```

which means that the rectangular web page designed has a length of 5 and a width of 5, with an area of 25 which is very close to the target area of 24.
