Think of the words “simplicity, performance and usability.” They were key components of Leaflet, an open-source JavaScript library for mobile-friendly interactive maps.

Leaflet was developed by Vladimir Agafonkin of MapBox, which is a building-block application that makes it easy to integrate location into mobile applications.

The library weighs about 33KB of gzipped JavaScript code, and it has all the features that most developers would ever need for online maps, according to the project’s GitHub page.

Leaflet works efficiently across all major desktop and mobile platforms out of the box, taking advantage of HTML5 and CSS3 on modern browsers while being accessible on older versions as well.

On their website, they offer tutorials with step-by-step code explanations, so even the “beginner JavaScript developers” can understand. Additionally, their GitHub explains that Leaflet can be extended with a huge amount of plug-ins, documented APIs and easy-to-read source code.
