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'
}
`

打开链接的 javascript.info Array 任务页面，并检查第二个任务“Array operations”及其提供的解决方案。检查该解决方案是否满足针对奇数长度的规定要求，并按描述替换中间值。当教程解决方案与针对奇数长度数组的说明一致时，即表示完成。
