Top EJS Alternatives for Streamlined JavaScript Templating
EJS, short for "Embedded JavaScript," offers a straightforward and powerful way to generate HTML markup using plain JavaScript. It's praised for its simplicity, speed, and ease of debugging, allowing developers to leverage their existing JavaScript knowledge without learning complex new syntax. However, like any tool, EJS might not be the perfect fit for every project or developer preference. This is where exploring an EJS alternative becomes essential, opening up a world of options that might better suit specific needs regarding features, performance, or community support.
Top EJS Alternatives
While EJS excels in its simplicity, a diverse ecosystem of templating engines and utility libraries offers compelling alternatives. Each comes with its own unique strengths, catering to different development styles and project requirements.

Underscore.js
Underscore.js is a utility-belt library for JavaScript that provides a lot of the functional programming support you would expect. While not a direct templating engine like EJS, it offers powerful developer tools and web development utilities that can complement or even facilitate certain templating needs, particularly for data manipulation before rendering. It's a Free and Open Source solution for the Web platform.

Pug
Pug, formerly known as Jade, is a high-performance template engine heavily influenced by Haml. Implemented with JavaScript for Node.js, it offers a concise and elegant syntax that can significantly reduce the amount of boilerplate code compared to EJS. Pug is Free and Open Source, available across Mac, Windows, Linux, and Self-Hosted environments, featuring robust developer tools and web development capabilities.

Lo-Dash
Lo-Dash is a popular drop-in replacement for Underscore.js, bringing significant performance improvements, bug fixes, and additional features. Like Underscore.js, Lo-Dash isn't strictly a templating engine but a utility library that enhances JavaScript development. Its focus on performance and robust features for data manipulation makes it an excellent Free and Open Source tool for web development, potentially simplifying the data preparation phase for any templating engine, including as an EJS alternative for data handling.

Handlebars
Handlebars is a powerful JavaScript template library based on Mustache. It provides the power necessary to build semantic templates effectively, with a logic-less approach that separates data from presentation. This makes Handlebars a strong EJS alternative for developers who prefer stricter separation of concerns and a more opinionated templating style. It is Free and Open Source, supporting Mac, Windows, Linux, and Web platforms for web development.

Eta JS
Eta JS is a lightweight, embedded, pluggable, and super-fast JavaScript template engine developed explicitly as an EJS alternative. It aims to be more lightweight, faster, and to solve several common issues found in EJS, offering features like custom delimiters. Eta JS is Free and Open Source, available for Web, JavaScript, GitHub, Node.JS, and npm environments, making it a direct and highly optimized choice for those looking to switch from EJS while retaining a similar JavaScript-centric approach.
Ultimately, the best EJS alternative depends on your specific project requirements, team familiarity with certain syntaxes, and performance needs. Whether you prioritize a logic-less approach, a more concise syntax, or enhanced performance, there's a powerful templating solution out there for you to explore.
