Handlebars
Handlebars is a popular templating engine for JavaScript that allows developers to build semantic templates effectively. It provides a simple syntax for embedding dynamic content into HTML by using expressions in double curly braces, making it easy to separate logic from presentation. It is often used in web development to generate dynamic HTML content on the client-side or server-side.
Developers should learn Handlebars when building dynamic web applications that require reusable HTML templates, such as in single-page applications (SPAs) or server-side rendering with Node.js. It is particularly useful for projects using frameworks like Ember.js, which integrates Handlebars as its default templating engine, or when working with static site generators to avoid repetitive code. Its minimal logic approach helps maintain clean, maintainable templates.
