A template engine allows you to use static template files in your project or application, then replaces variables/instances declared in a template file with actual values at run-time.
For example, a common use is templating elements like headers and footers.
Today, we bring you 2 template engines you must try.
Pug (also known as Jade)
To understand Pug we need to remember that the browser reads HTML and CSS and then displays formatted images and text to the client based on what that HTML and CSS tells it to do.

You can convert HTML to PUG here: https://html-to-pug.com/
Handlebars is a logic-less templating engine that dynamically generates your HTML page. It’s and extension of mustache with a few additional features. Mustache is fully logic-less but Handlebars adds minimal logic thanks to the use of some helpers (such as if, with, unless, each and more).
How does Handlebars work?
1- Handlebars takes a template with the variables and compiles it into a function.
2- This function is then executed by passing a JSON object as an argument. This JSON object is known as context and it contains the values of the variables used in the template.
3- On its execution, the function returns the required HTML after replacing the variables of the template with their corresponding values.

Conclusion – Which is the best one?
I have tried both template engines (both are good) but I can tell you that Handlebars is the best and easier option to go.
Templating with pug is better, I mean, you don’t need to pre-compile before actually see potential changes. But you will have .pug files instead of html and you will need to learn pug syntaxes.
