How to create feature layer using local json file in arcgis API for javascript 4?

[BahaaZidan]

i'm new to using arcgis javascript api and to data visualization in general . my supposed use case is the following ::

supposedly i have a database of employees information that's stored in JSON format like this :: 

[

   {
      "name":"lorem ipsum",
      "role":"software engineer",
      "location":"london, uk"
   } ,,,,,,,

]

how can i represent this data on an arcgis map ?? i'm a complete novice so any advice would be appreciated .

i've been drowning in the sample code section of the docs but really didn't get my answer.

thanks in advance .

I recommend checking out the ArcGIS DevLabs: Get Started with ArcGIS DevLabs | ArcGIS for Developers. They are designed to help walk you thru how the pieces fit together starting at working with geographic Data, learning about cartographic Design and then pulling it all together in an application that you Develop.
