Average Salary (Indicative for roles leveraging TypeScript skills in India, circa 2021): While specific salary data for 2021 for India is variable, roles requiring TypeScript expertise were generally well-compensated, often aligning with or slightly exceeding average salaries for experienced JavaScript developers.
Go: Google’s Language for Efficiency and Concurrency
Go, often referred to as Golang, is a language developed at Google with a strong emphasis on simplicity, concurrency, and high performance. For engineers in India aiming for roles in systems programming or backend development, Go presented a compelling option in 2021 and continues to do so. It shares many capabilities with languages like C and C++ but boasts a simpler, more modern syntax, making it potentially easier to learn and use for certain applications. Go is particularly well-suited for building web servers, managing data pipelines, and even developing machine learning tools.
Key Features of Go:
- Concurrency Focus: Go’s built-in concurrency features simplify the management of multiple tasks simultaneously, crucial for modern applications.
- Readability and Simplicity: Go’s clean and straightforward syntax enhances code readability and makes maintenance more manageable.
- Garbage Collection: Automatic memory management reduces the burden on developers, simplifying development and reducing memory-related errors.
| Pros of Go | Cons of Go |
|---|---|
| Relatively easy to learn, especially for those with programming fundamentals | Ecosystem, while growing, may not be as extensive as older languages |
| Excellent built-in support for concurrency and parallelism | Might not be the ideal choice for every programming paradigm, such as GUI-heavy applications |
| Provides efficient performance, suitable for demanding applications | Can have a steeper learning curve when tackling very complex system-level projects |
Prerequisites: A foundational understanding of basic programming concepts is generally sufficient to begin learning Go.
Skills Needed: An interest in and understanding of system-level operations and architecture is advantageous for Go development.
Platform: Go is designed to be cross-platform, supporting Windows, Linux, and macOS.
Use Cases:
- Building highly scalable web services and robust APIs.
- Network programming and development of system-level tools.
- Development of cloud-native applications, leveraging its efficiency and concurrency.
Average Salary (Indicative for roles leveraging Go skills in India, circa 2021): Go developers were in high demand in 2021 in India, particularly in companies focusing on backend infrastructure and scalable systems. Salaries were competitive, often reflecting the specialized skills required.
Swift: Apple’s Choice for Modern App Development
Swift emerged as the primary language for developing applications within the Apple ecosystem by 2021, targeting iOS, iPadOS, macOS, watchOS, and tvOS. Introduced by Apple in 2014, Swift was a relatively new language at the time, purpose-built for modern Apple platform development. Optimized for performance and designed to address the demands of contemporary iOS development, Swift was a top recommendation for aspiring iOS developers in India. With the consistent popularity and profitability of Apple products, developers skilled in Swift were, and continue to be, highly sought after.
Key Features of Swift:
- Modern and Safe Design: Swift features a syntax that is safe, readable, and expressive, promoting efficient and less error-prone development.
- Seamless Platform Integration: Swift is deeply integrated with Apple’s development tools (Xcode) and frameworks (like Cocoa Touch and SwiftUI), providing a streamlined development experience.
- Emphasis on Safety: Swift prioritizes memory safety and type safety, helping to minimize crashes and runtime errors, leading to more stable applications.
| Pros of Swift | Cons of Swift |
|---|---|
| Promotes safe and readable code, reducing common programming errors | Primarily used for Apple platforms, limiting its versatility outside the Apple ecosystem |
| Powerful and expressive language, enabling complex and feature-rich applications | Smaller developer community compared to more universally adopted languages, though rapidly growing within the Apple domain |
| Modern and efficient, taking advantage of the latest programming paradigms | May require a learning curve for developers not already familiar with Apple’s development environment and tools |
Prerequisites: An interest in developing applications for Apple devices and understanding of iOS ecosystem is ideal.
Skills Needed: Familiarity with Apple’s development tools, particularly Xcode, is essential for Swift development.
Platform: Exclusively for Apple platforms: iOS, iPadOS, macOS, watchOS, and tvOS.

C#: Microsoft’s Versatile Language Across Platforms
Similar to C++, C# (pronounced C Sharp) is a versatile, object-oriented programming language that builds upon the foundations of C. Originally developed by Microsoft as part of its .NET framework, C# was initially heavily associated with Windows application development. C# adopts a syntax that is similar to other languages in the C family, such as C++, making it easier for developers with experience in those languages to learn.
Key Features of C#:
- Object-Oriented Programming: C# is strongly object-oriented, promoting code organization, reusability, and modular design through objects and classes.
- .NET Framework and Ecosystem: Seamless integration with the .NET framework provides access to a vast library of tools and functionalities, accelerating development.
- Cross-Platform Capabilities: With the advent of .NET Core (and subsequent versions), C# applications gained cross-platform capability, running on Windows, macOS, and Linux.
| Pros of C# | Cons of C# |
|---|---|
| A powerful and highly versatile language suitable for a wide range of applications | Can have a steeper initial learning curve for absolute beginners to programming |
| Large and active community with extensive resources, documentation, and support | Historically, it was primarily focused on Microsoft environments, though this is changing with .NET Core and later |
| Strong object-oriented principles encourage good software design and maintainability | May not be the optimal choice for certain niche programming tasks where other languages might be more specialized |
Prerequisites: While not strictly necessary, prior experience with programming languages, particularly those in the C family, can be helpful when learning C#.
