Traversals: Starting from Scratch
ArangoDB provides the edges, inEdges, and outEdges methods for edge collections. These methods can be used to quickly determine if a vertex is connected to other vertices, and which.

For example, to determine which edges are linked to the world vertex, we can use inEdges:

db.e.inEdges('v/world').forEach(function(edge) {
  require("internal").print(edge._from, "->", edge.type, "->", edge._to);

The result is a JavaScript array that we can iterate over and print the results:

v/continent-africa -> is-in -> v/world
v/continent-south-america -> is-in -> v/world
v/continent-asia -> is-in -> v/world
v/continent-australia -> is-in -> v/world
v/continent-europe -> is-in -> v/world
v/continent-north-america -> is-in -> v/world
