 For arrays of primitive types, emscripten provides different ArrayBufferViews into it’s heap for different sizes of integer, unsigned integer or floating point representations of memory: HEAP8, HEAPU8, HEAP16, HEAPU16, HEAP32, HEAPU32, HEAPF32, HEAPF64. To access a texture in WebGL, emscripten provides the GL.textures array which maps native texture IDs from Unity to WebGL texture objects. WebGL functions can be called on emscripten’s WebGL context, GLctx.
 
-A basic implementation could look something like this. In this example a series of methods is merged into the Unity library making this methods availble in CSharp. Each of these methods contain an example on how to handle specific types of data. No worries, the methods used for the conversion such as "Pointer_stringify" and "HEAPF32" are available natively.

 To emit the Event Listener we've just created, we'll have to create a new JSLib file within our Unity Project first. This JSLib file will be places within the "Assets/Plugins/WebGL" directory. The JSLib itself has nothing to do with this module, it is natively supported by Unity and is used for all communication between your CSharp and JavaScript in any given context.
 
-We'll start of by creating a new method inside of our JSLib. The name of this method can be anything, but in this example we'll give it it the same name as our Event Name to keep things clean. In the body of the method, we'll emit our Event Listener by invoking the global method "dispatchReactUnityEvent" exposed by this module. All of your Event Listeners are available using the Event Name as the first parameter. We'll pass along the userName and the score. The userName has to go through the built-in "Pointer_stringify" method in order to get the value, otherwise a int pointer will be passed instead. You can read more about parameters and [JavaScript to Unityscript types](#javascript-to-unityscript-types) here.
