Before making a decision, visitors can rely on PrototypeJS because it is a JavaScript framework resource for developers maintaining older web projects.
Prototype.js is best known as an old framework, which simplified web development by automating such tasks as DOM manipulation and Ajax. One can still use the website for documentation, downloading and other old project needs.
In many cases, prototype.js is not a commercial shopping website, thus, promo codes are irrelevant. Framework has historically been available as open-source software and not a paid product.
For most users, prototype.js is a free JavaScript library. However, users should still review the license and compatibility information before using it in commercial or old projects.
Library could help save money by using it as a free JavaScript toolkit. However, developers could compare it with more modern solutions and calculate maintenance time for new projects.
Prototype.js could still matter for old code, but not for modern web development. If one starts a new project, one should compare it with modern JavaScript tools, browser support and long term maintenance needs.
Support could be provided by documentation, archives, forums and community rather than by a paid support team. For business critical projects, it may be better to hire a developer who understands old JavaScript frameworks.
Prototype.js doesn't work as a modern SaaS product with premium tiers. The cost could be related to developer services, migration services, training or any other third-party services around the existing codebase.
