Handlebars features and specs

  • Simplicity
    Handlebars provides a straightforward and easy-to-learn syntax for templating, making it accessible for developers with varying levels of experience.
  • Logic-less Templates
    Encourages the separation of logic and design by only allowing minimal logic in templates. This promotes a cleaner code base and separation of concerns.
  • Extensibility
    Handlebars allows for custom helpers and partials which enable extending the templating functionality as needed.
  • Precompilation
    Templates can be precompiled, improving performance by reducing client-side parsing and rendering time.
  • Wide Adoption and Community Support
    As a popular templating engine, Handlebars has a large community of users and contributors, which provides abundant resources, plugins, and support.

Possible disadvantages of Handlebars

  • Limited Logic
    The logic-less nature of Handlebars means it supports only very basic conditionals and loops, which can be limiting for complex scenarios.
  • Verbosity
    Handlebars templates can become verbose, especially when using custom helpers or partials extensively.
  • Initial Learning Curve
    For developers coming from more logic-oriented templating engines, adjusting to Handlebars' logic-less paradigm can take some effort.
  • Dependency Management
    In larger projects, managing dependencies between templates, partials, and helpers can become complex and cumbersome.
  • Lack of Reactivity
    Handlebars does not include built-in support for data reactivity, making it less suitable for dynamic, real-time updates compared to modern frameworks like React or Vue.

Underscore.js features and specs

  • Utility Functions
    Underscore.js provides a wealth of utility functions for common tasks such as map, reduce, filter, and more, making it easier to perform operations on arrays, objects, and collections.
  • Consistency
    The library offers a consistent API, which can make your code more readable and maintainable by providing a standard way to perform common programming tasks.
  • Lightweight
    Underscore.js is lightweight compared to full-featured libraries like Lodash, which can be a benefit if you're looking to minimize your application's footprint.
  • Browser Compatibility
    It supports a wide range of JavaScript environments, making it a good choice for projects that need to work across different browsers and Node.js.
  • Quick to Learn
    Easy to pick up for developers with even a basic understanding of JavaScript, due to its straightforward documentation and familiar function names.

Possible disadvantages of Underscore.js

  • Performance
    Underscore.js may not offer the same level of performance optimizations as more modern utility libraries like Lodash, potentially leading to slower execution for some tasks.
  • Limited Functionality
    While it covers many basic utility functions, its feature set is not as extensive as Lodash or other similar libraries, which provide a broader range of capabilities.
  • Outdated
    With the advent of ECMAScript 5 and later versions, many of the functions provided by Underscore.js are now natively available in JavaScript, reducing its necessity.
  • No Modularization
    Underscore does not support modular builds in the same way Lodash does, meaning you might end up including the entire library even if you only need a few functions.
  • Community and Maintenance
    While still maintained, Underscore.js has seen less active development and contributions compared to newer libraries, which could impact its long-term viability and support.

  • Chapter 7: HTML part two
    For a more robust approach, we'd probably need to install a templating language of some kind, such as Twig, EJS, Handlebars, Pug or Mustache (this is not a complete list!). Reading the documentation for posthtml-modules, you'll notice it doesn't mention package.json or any of the approaches we've used in this guide. Instead, the examples are in JavaScript and we've advised to add this to our Node application. - Source: dev.to / 2 months ago
  • How to send emails using Express and NodeJS
    As suggested by a teammate, I found out that I'll need to create the template in a different file and then replace the variables in it using some utility. So, again after searching for some packages, I figured that Handlebars would be the best solution for our problem. - Source: dev.to / 7 months ago
  • The Features of Front-end UI Components
    In dynamic web pages, especially when using template engines such as Mustache and Handlebars or libraries/frameworks such as React and Vue, the final content structure is basically generated by JS, which strengthens JS and weakens the control of HTML over the content structure. - Source: dev.to / 4 months ago
  • Make Custom Handlebar Helpers in Ghost!
    In this variable, we have the response from the Ghost instance as the full HTML of the page. Imagine that this response is the homepage of your Ghost instance. The HTML content will also include our plain text {{hello_world}}, which is displayed as plain text. If our custom helper is in this form, we can compile it using Handlebars.js (https://handlebarsjs.com/) in our middleware. Remember to install the library... - Source: dev.to / 4 months ago
  • htmx and ExpressJS
    It is a novel experience to say the least for me. I mean yes I have been using Handlebars, pug, and other templating engines but this is novel in how it changed my perspective about HTML (Just read their motivation in htmx.org). - Source: dev.to / 7 months ago

  • JavaScript evolution: From Lodash and Underscore to vanilla
    Underscore was created by Jeremy Ashkenas (the creator of Backbone.js) in 2009 to provide a set of utility functions that JavaScript lacked at the time. It was also created to work with Backbone.js, but it slowly became a favorite among developers who needed utility functions that they could just call and get stuff done with without having to worry about the inner implementations and browser compatibility. - Source: dev.to / 5 months ago
  • KlongPy: High-Performance Array Programming in Python
    There was a step-change improvement for me when I tried expressing some JS patterns via `underscore.js` instead of procedurally: eg: http://underscorejs.org/#each Thinking of something as `each | map | filter | sum` is waaay less buggy than writing bespoke procedural code to do the same thing. No doubt there is a "cost" to it as well, but the _abstraction_ is valuable. Now, if there were a "compiler" which could... - Source: Hacker News / 5 months ago

    Not too far behind is Underscore.js, another utility library that's all about enhancing your JavaScript mojo. Whether you're dealing with arrays, objects, or strings, Underscore has got something for you. It's like Lodash's sibling, offering similar functionalities but with its own flair. The choice between them is like picking between chocolate and vanilla - it really comes down to personal taste. - Source: dev.to / about 1 year ago
