Stop Using Multiple Languages


The use of multiple programming languages in software development has become increasingly common in recent years. While the diversity of languages offers various benefits, it also presents several challenges. This outline explores the rationale behind considering a more restrained approach to language usage in programming, highlighting the complexities, advantages, and best practices associated with this issue. It ultimately seeks to encourage a thoughtful and balanced approach to programming language selection in software development projects.

The Challenges of Using Many Languages

Incorporating numerous programming languages into a software development project can introduce a range of significant challenges that developers and teams must contend with. These challenges include:

A. Complexity and Maintenance

  1. Managing codebases written in multiple languages can lead to increased complexity.
  2. Frequent updates and maintenance become cumbersome when dealing with various language-specific code segments.

B. Integration Difficulties

  1. Ensuring seamless interaction and data exchange between different language components can be challenging.
  2. Integration bugs may arise due to language incompatibilities, leading to a suboptimal user experience.

C. Skill and Expertise Requirements

  1. Developers need expertise in multiple languages, increasing the learning curve and potentially limiting the available talent pool.
  2. Maintaining proficiency in numerous languages can be time-consuming and resource-intensive.

D. Reduced Code Readability

  1. Mixing languages within a project can result in code that is harder to understand and maintain.
  2. Collaboration and code review processes become more error-prone, potentially leading to increased debugging efforts.

Addressing these challenges is crucial to achieving efficient and sustainable software development practices.

Advantages of Using Fewer Languages

Opting for a more limited set of programming languages in software development projects offers several advantages that can streamline the development process and improve overall project outcomes. These advantages include:

A. Improved Codebase Consistency

  1. Fewer languages lead to more consistent coding styles and practices.
  2. Codebase uniformity enhances readability and reduces the chances of errors caused by language-specific idiosyncrasies.

B. Easier Team Collaboration

  1. A reduced language set promotes better communication and collaboration among team members.
  2. Developers can more readily understand and contribute to different parts of the project.

C. Enhanced Debugging and Troubleshooting

  1. With fewer languages, it's easier to pinpoint and resolve issues within the codebase.
  2. Debugging becomes more efficient as developers become more proficient in a smaller set of languages.

D. Reduced Development Time and Cost

  1. Learning and maintaining expertise in fewer languages saves time and resources.
  2. Projects can progress more swiftly, leading to cost savings and quicker time-to-market.

By focusing on the advantages of using fewer languages, development teams can streamline their workflows, improve code quality, and enhance overall project efficiency.

Best Practices for Language Usage

Adopting a strategic approach to language usage is crucial to reap the benefits of a streamlined development process. The following best practices guide developers and teams in making informed language choices and optimizing their usage:

A. Standardization within Teams

  1. Establish coding guidelines and standards that apply consistently across all selected languages.
  2. Regularly review and update these standards to reflect best practices and evolving project requirements.

B. Using Language Features Wisely

  1. Make deliberate choices when selecting specific language features for each task.
  2. Avoid unnecessary complexity by refraining from using features that do not add value to the project.

C. Regularly Reviewing and Updating Language Choices

  1. Periodically assess the suitability of chosen languages for the project's evolving needs.
  2. Be prepared to adapt and change languages when a better fit becomes available or requirements change.

D. Leveraging Polyglotism When Necessary

  1. If the project genuinely demands multiple languages, ensure a clear and documented rationale for each language's inclusion.
  2. Implement integration mechanisms that minimize friction between different language components.

By adhering to these best practices, development teams can strike a balance between language diversity and project efficiency, ultimately leading to more successful and maintainable software projects.

Factors to Consider When Choosing Languages

Selecting the appropriate programming languages for a software development project requires careful consideration of several key factors. These factors help ensure that the chosen languages align with project goals and constraints. Considerations include:

A. Project Requirements

  1. Assess the project's specific functional and non-functional requirements.
  2. Choose languages that are well-suited to meet these requirements, such as performance, scalability, and platform compatibility.

B. Team Expertise

  1. Evaluate the proficiency and familiarity of the development team with various languages.
  2. Opt for languages that match the team's expertise to expedite development and reduce the learning curve.

C. Community Support

  1. Investigate the strength and activity of the language's developer community.
  2. Languages with robust communities tend to offer better support, libraries, and resources.

D. Ecosystem and Tooling

  1. Consider the availability of development tools, frameworks, and libraries in each language.
  2. A rich ecosystem can enhance productivity and reduce development time.

By carefully weighing these factors, project stakeholders can make informed decisions about the programming languages that best align with the project's goals, resources, and team capabilities.


In the ever-evolving landscape of software development, the choice of programming languages is a pivotal decision that can significantly impact project success. While the use of multiple languages can provide versatility, it's imperative to balance this diversity with thoughtful consideration.

By understanding the challenges associated with using many languages, recognizing the advantages of using fewer languages, and following best practices for language usage, development teams can achieve greater efficiency, maintainability, and collaboration.

Moreover, the factors discussed for selecting languages underscore the importance of aligning language choices with project requirements, team expertise, community support, and available tooling.

In conclusion, the judicious selection and balanced use of programming languages are essential for the success of software development projects. A strategic approach that combines flexibility with standardization can help teams navigate the complex landscape of programming languages and ultimately deliver more robust and efficient software solutions.

The title is a bit misleading I would say, it should be something like "Don't use more languages than you really need on a project" ...

I mean, how would you develop your average web app using a commonly used stack without at least using HTML, CSS and Javascript?

That's 3 languages right there ... even when you say "HTML and CSS aren't real languages", it's pretty common to use a different language for the backend and for the frontend (not everyone wants to use NodeJS for their backend).

But I agree that people shouldn't gratuitously use half a dozen languages on a project, when there's no real need to do so.

Great article. This makes me think of the KISS principle. I find often we need to go back to first principals, and stop over engineering.

I will say though - it's important to learn multiple languages, and I highly recommend Golang. In 2023 when we are so use to importing packages all over the place, Golang teaches you minimalism and you can focus on design patterns - which is more important than language X or Y.

I started Python in the beginning and transitioned into JS. I have also tried C++
