Fork, Commit, Merge - Medium Issue (TypeScript)

Create a simple calculator in TypeScript that can perform basic arithmetic operations (addition, subtraction, multiplication, and division)

Note: You don't have ask permission to start solving the issue or get assigned, since these issues are supposed to be always open for new contributors. The actions-user bot will reset the file back to previous state for the next contributor after your commit is merged. So you can just simply start working with the issue right away!

Description

Create a TypeScript namespace named Calculator.

The Calculator namespace should have the following methods:

• add(a: number, b: number): number: Returns the sum of a and b.
• subtract(a: number, b: number): number: Returns the result of a minus b.
• multiply(a: number, b: number): number: Returns the product of a and b.
• divide(a: number, b: number): number: Returns the quotient of a divided by b. If b is 0, it should return null (or optionally throw an error).

Ensure to handle edge cases and provide proper type annotations.

Hints:

• Make use of TypeScript's strong typing features to ensure the correct types are being passed and returned.
• Handle division by zero carefully. You can either return null or throw a custom error.

Acceptance Criteria:

• The calculator must be implemented in a type-safe manner using TypeScript.
• Each method should work as expected for basic arithmetic operations.

How to get started

First, run npm i from the root of the project to get all the necessary dependencies.
The, open the tasks/typescript/medium directory.

Once you have created the calculator, you can test your solution with this command:

npx ts-node tasks/typescript/medium/calculator.ts

If your solution works, the tests should return these values:

8
2
15
1.666...
Warning message & null

If the values look correct, you are ready to make a Pull request!
