Dart vs Go vs JavaScript: What are the differences?

## Introduction
In this Markdown formatted content, we will discuss the key differences between Dart and Go and JavaScript.

1. **Typing System**: Dart and Go both have a strong static typing system, requiring developers to define the type of variables explicitly, whereas JavaScript is dynamically typed, allowing flexibility but potentially leading to runtime errors due to type mismatches.
   
2. **Concurrency Support**: Go is designed with built-in support for concurrency through goroutines and channels, making it easier to write concurrent programs compared to Dart and JavaScript, which rely on event loops and callbacks for asynchronous operations.
   
3. **Compilation**: Go compiles to machine code directly, making it highly efficient in terms of performance, while Dart and JavaScript are often interpreted or transpired to JavaScript in the case of Dart, which can impact performance.
   
4. **Tooling**: Go comes with a powerful set of tools for formatting, testing, and profiling code, providing a seamless development experience, whereas Dart has a more focused set of tools, and JavaScript relies on third-party tools and libraries for similar functionalities.
   
5. **Error Handling**: Dart and Go enforce strict error handling through mechanisms like error types and defer statements, ensuring structured error management, while JavaScript has looser error handling, relying more on try-catch blocks.
   
6. **Garbage Collection**: Go utilizes a concurrent garbage collector that manages memory efficiently without interrupting the program's execution, a feature lacking in Dart and JavaScript, which rely on different garbage collection strategies that might impact performance.

In Summary, key differences between Dart, Go, and JavaScript encompass typing system, concurrency support, compilation, tooling, error handling, and garbage collection methods.
