What is the difference between geometry and features in GeoJSON?
Geometries are the central part of GeoJSON, therefore, the real world data is more than theses simple shapes having identity and attributes. Features records the geometry as well as their properties. A feature properties can be a type of JSON object contain single-depth key value mappings.
When was GeoJSON developed?
The GeoJSON format working group and discussion were begun in March 2007 and the format specification was finalized in June 2008. In April 2015 the Internet Engineering Task Force has founded the Geographic JSON working group which released GeoJSON as RFC 7946 in August 2016.

JSON file created in the GeoJSON format, a format used for geospatial data interchange; supports points, lines, polygons, and other similar primitives; used for defining objects such as roads, bodies of water, buildings, and points of interest.
What does GeoJSON data look like?
Coordinates in GeoJSON are formatted like numbers in JSON: in a simple decimal format. Unlike geographic data for human consumption, data formats never use non-base-10 encodings like sexagesimal. As cool as 8° 10' 23” looks, it's just not a very good way to tell numbers to computers.

What is the difference between shapefile and GeoJSON?
For a similar number of vector features with attributes, GeoJSON has almost double the file size compared to shapefile in most cases. GeoJSONs have no spatial indexing. So, it's tough to handle when dealing with a large number of features.

Is GeoJSON better than KML?
GEOJSON is in my opinion, the best format, it is easy to read, easy to use in javascript and generally smaller in size then GML/KML. It can even contain info about style, see here. It not a official standard, but it is supported on both leaflet and openlayers and on many gis-desktop apps like qgis.

Technically, Yes. GeoJSON is also at the end of the day JSON, you can save it as a .json file as well, given that you follow the standard mentioned earlier
Is GeoJSON a vector?
GeoJSON is a vector file, hence it doesn't have a sense of style in itself. Tools such as QGIS, or anyGeoJSON has a default style feature which will enable you to visualize the data on the map, it is important to set the map in the same CRS of GeoJSON, otherwise, it might create false results.
What is a GeoJSON file?
GeoJSON is a JSON based format designed to represent the geographical features with their non-spatial attributes. This format defines different JSON (JavaScript Object Notation) objects and their joining fashion. JSON format represents a collective information about the Geographical features, their spatial extents, and properties. An object of this file may indicate a geometry (Point, LineString, Polygon), a feature or collection of features. The features reflect addresses and places as point’s streets, main roads and borders as line strings and countries, provinces, and land regions as polygons. Using the GeoJSON, different mobile routing and navigation applications can indicate the coverage of their services. An extension of GeoJSON is TopoJSON that is smaller in size and encodes geospatial topology.
