How does @babel/types.isTSTupleType work?

@babel/types.isTSTupleType is a function from the @babel/types package in JavaScript that checks whether a given object is a Typescript tuple type or not.

A tuple type is a fixed-length array type in Typescript where the type of each element in the array is known in advance. The syntax for defining a tuple type in Typescript is [Type1, Type2, ..., TypeN].

To determine whether an object is a tuple type using @babel/types.isTSTupleType, the function checks if the object has a type property with a value of TSTupleType. If so, it returns true. Otherwise, it returns false.

For example, consider the following Typescript tuple type:

typescript
type MyTuple = [string, number];

To check if an object is an instance of this tuple type, we could use @babel/types.isTSTupleType as follows:

javascript
const t = require('@babel/types');

const myObj = { type: 'TSTupleType', elements: [ { type: 'StringType' }, { type: 'NumberType' } ] };

console.log(t.isTSTupleType(myObj)); // true

In this example, we create an object myObj that represents a tuple type with two elements: a string and a number. We then pass this object to @babel/types.isTSTupleType, which returns true because the object has a type property with a value of TSTupleType.

const t = require("@babel/types");

const node = t.tsTupleType([t.tsNumberKeyword(), t.tsStringKeyword()]);

console.log(t.isTSTupleType(node)); // true

In this example, we first create a tuple type node using the t.tsTupleType method from the Babel types module. We then pass this node to @babel/types.isTSTupleType to determine whether or not it represents a tuple type. The function returns true, indicating that the node is indeed a tuple type.
