Convert JSON to TypeScript type

1. Converting JSON-formatted arrays to TypeScript types allows potential errors to be detected during compilation, reduces runtime issues, and makes the code more reliable, especially in large projects.

2. Introduction to some types:

(1) number: Represents numeric values, which can be integers or floating-point numbers.

(2) string: Represents text values.

(3) boolean: Represents Boolean values, i.e., true or false.

(4) null and undefined: Represent null values and undefined values, respectively.

(5) Array: An array type where the elements are text values.

(6) Array: An array type where the elements are numeric values.

(7) `any`: Represents any type, including but not limited to numbers, strings, booleans, objects, arrays, etc.

(8) `Date`: Represents the date type.

(9) `Function`: A generic type representing any function (suitable for scenarios requiring dynamic function handling, but be aware of potential type safety issues).
