Mapbox GL
The "GL" in Mapbox GL JS refers to Mapbox GL, a graphics library that renders 2D and 3D Mapbox maps as dynamic visual graphics with OpenGLin any compatible web browser, without using additional plugins.
Client-side rendering
Mapbox GL JS relies on client-side rendering. Mapbox GL JS maps are dynamically rendered by combining vector tiles with style rules in the browser rather than on a server, which makes it possible to change the maps's style and displayed data in response to user interaction.
The Map class
The mapboxgl.Mapclass is the basis of every Mapbox GL JS project. The example code in this section demonstrates the minimum you need to add a map to your page: 1. accessToken: This Mapbox access tokenassociates your Mapbox GL JS map with a Mapbox account. 2. container: The HTML element in which the map will be placed.

Mar 3, 2021 · A powerful feature of Mapbox GL JS is that you can style map layers when they are added to the map or after. This provides a lot of flexibility in terms of allowing your map styles to adapt to changes in your application.
This example uses a new slot property to add a layer to a predetermined location in the Standard style. Set the preferred slot on the Layer object before adding it to your map and your layer will be appropriately placed in the Standard style's layer stack.
