Features and specs

What each product offers, as listed by its team.

JaamSim Pro 5 features
Modular JavaScript 5 features
  • Ideal for Digital Twins
    Create, maintain, and audit the most complex models
  • Scalable to huge models
    Define 10,000 or more objects
  • Faster execution
    5 - 10 times faster execution speed than other software
  • Text input files
    Allow the use of Git for version control
  • Based on open-source software
    Free, open-source version of JaamSim has been downloaded more than 120,000 times
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Analysis

An editorial look at what each product does well and who it suits.

JaamSim Pro
Modular JavaScript

Overall verdict

  • JaamSim Pro appears to be a commercially supported version of the open-source JaamSim discrete-event simulation engine, aimed at businesses that want the modeling power of JaamSim plus professional support, added features, and easier deployment. It's a solid choice for organizations needing simulation capabilities without building everything from scratch on the open-source core, though it may lack the polish, ecosystem, and market presence of established simulation platforms like AnyLogic, Arena, or Simio.

Why this product is good

  • Built on the proven JaamSim open-source discrete-event simulation framework, which has a track record in industries like mining, logistics, and manufacturing
  • Likely offers commercial support, documentation, and possibly enhanced UI/UX on top of the free open-source version
  • Discrete-event simulation is well-suited for modeling complex systems such as production lines, supply chains, and queuing systems
  • Potentially lower licensing cost compared to major commercial simulation suites since it leverages an open-source base
  • Java-based architecture (inherited from JaamSim) allows for cross-platform use and extensibility via scripting/customization

Recommended for

  • Engineers and analysts needing discrete-event simulation for process optimization
  • Companies wanting professional support around an open-source simulation core rather than building in-house tools
  • Mining, manufacturing, and logistics operations modeling material flow and system throughput
  • Organizations with budget constraints seeking an alternative to expensive enterprise simulation software
  • Users already familiar with or invested in the JaamSim open-source ecosystem who want added commercial features

Overall verdict

  • Modular JavaScript (mjavascript.com) is a solid resource for developers looking to learn best practices around modular design patterns in JavaScript, though its value depends on your current skill level and how current the content remains given the fast pace of JS ecosystem changes.

Why this product is good

  • Focuses specifically on modularity, a critical but often overlooked aspect of scalable JavaScript development
  • Covers practical patterns for organizing code, managing dependencies, and structuring larger applications
  • Can help bridge the gap between basic JavaScript knowledge and professional-grade architecture skills
  • Often includes real-world examples rather than purely theoretical concepts
  • Useful for understanding module systems like CommonJS, ES Modules, and build tool configurations

Recommended for

  • Intermediate JavaScript developers wanting to level up their code organization skills
  • Developers transitioning from simple scripts to larger, maintainable applications
  • Teams looking to establish consistent modular coding standards
  • Self-taught programmers seeking structured guidance on architecture
  • Backend or frontend developers working with Node.js or modern JS frameworks who need better module management practices

Questions & Answers

As answered by people managing JaamSim Pro and Modular JavaScript.

Who are some of the biggest customers of your product?

JaamSim Pro's answer

  • Hypercube Scientific
  • Anglo American
  • Fortescue Metals Group (FMG)
  • Entech
  • InterMat

What makes your product unique?

JaamSim Pro's answer

Models involving material flow/storage and vehicle motion can be constructed much more easily. The models execute 5 - 10 times faster than all other software. Human readable input files allow models with thousands of objects to be constructed and maintained easily using standard version control software such as Git.

Why should a person choose your product over its competitors?

JaamSim Pro's answer

Easier to construct industry-sized models and these model execute 5 - 10 times faster than competing software.

How would you describe the primary audience of your product?

JaamSim Pro's answer

Simulation engineers working in the mining, oil & gas, rail, and shipping industries.

What's the story behind your product?

JaamSim Pro's answer

Based on the free open-source simulation software 'JaamSim'. New libraries of objects were created to model the production, storage, and shipping of bulk products such as iron ore, crude oil, LNG, etc.

Which are the primary technologies used for building your product?

JaamSim Pro's answer

Java, OpenGL, and JOGL software are used. We developed our own engines for discrete-event simulation and 3d graphics, which is why the software is so fast.
