Currently diving into TypeScript and tackling some TDD challenges. Within my model file, I'm working with a property named 'innovatorQuotes' that should be an array containing strings with a fixed length of 3. I'm struggling to nail down how to accomplish this goal. The current line in my code is:
innovatorQuotes: types.optional(types.array(types.string), []),If anyone has insights on how to set the expected length to 3, your input would be greatly appreciated! Thank you!
One potential solution could be implementing the following:
quoteList: [string, string, string]
It is important to note that TypeScript's validation applies during compile time and may not catch runtime errors such as exceeding the defined array length when using methods like .push.
