# Simple String Calculator
This is a simple string calculator implemented in JavaScript project, that serves as a task aimed at learning JavaScript unit testing with Jest. The calculator function, calc, accepts mathematical expressions in the form of strings and evaluates them to return the result. The calculator supports basic arithmetic operations such as addition, subtraction, multiplication, and division.
## 🧮 Features
- Supports addition, subtraction, multiplication, and division.
- Handles negative numbers and decimal numbers correctly.
- Follows the correct order of operations.
- Throws errors for division by zero, invalid operators, and invalid input types.
- Ignores numbers larger than 1000 when adding.
- Comprehensive unit tests using Jest for ensuring functionality and reliability.
- Achieves 100% test coverage to validate all aspects of the calculator function.
