JSON to TypeScript

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-scale 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 a Boolean value, i.e., true or false.

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

(5) Array<string>: An array type where the elements are of the string type.

(6) Array<number>: 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).
