Array Task Solution Clarification

Data Types > Arrays > Tasks > Second Task 'Array operations.'
https://javascript.info/array#tasks

Instruction 3 states:

> "Replace the value in the middle by "Classics". Your code for finding the middle value should work for any arrays with odd length."

This specifies that we should **replace** the middle value, and that our code should work for any arrays with an **odd** length.

The solution provided does not include a condition, and will always replace a value in an array, regardless of it's length.

Consider adding:

`
if (styles.length % 2 !== 0) {
styles[Math.floor(styles.length / 2)] = 'Classics'
}
`

開啟連結的 javascript.info Array 任務頁面，並檢查第二個任務「Array operations」及其提供的解決方案。檢查該解決方案是否符合針對奇數長度所述的要求，並如描述般替換中間值。當教學解決方案與針對奇數長度陣列的指示一致時，即表示完成。
