Why not something as simple as:
for each(var role in roles) {
if(role == desiredRole)
return true;
}
return false;

Subject: [Neo4j] Looking for value from array-typed relationship property in
traversal return filters (REST API)
Hi there,
I am getting pretty excited with the power of return evaluators in
traversing framework. However, since I am using the REST API, there
are certainly some restrictions.
I should build a return filter to return nodes with an incoming
relationship containing a certain value in one of its array-typed
properties. So far I have managed to build following query:
"return filter" : {
"language" : "javascript",
"body" : "if (position.length() > 0) {
var r = position.lastRelationship();
if (r.hasProperty('roles')) {
var roles = r.getProperty('roles');
// Something must be done here and end up
with true or false...
} else {
false;
}
} else {
false;
}"
}
An example of the relationship data is here:
"data" : {
"roles" : ["super","admin","user"]
}
There is a comment "// Something must be done here...." in the
evaluator where I haven't been able to figure out anything to. How
could I test if roles variable has a certain value in it? I tried
different functions, but no luck yet.
Best regards,
Ville
