How do i...i got syntax error while creating array of objects

I think you need to rethink how you're structuring this access list. The semantics you're using don't fit together with what it is you're trying to accomplish.

[ A, B, C ] defines an array, which means it can contain elements but you cannot specify the A: B relationship. It's not designed for that.

{ A: B, C: D } defines an object, which means you can define the A: B relationship, and arrays must be included as a child property.

From your example you probably need to choose whether you want one of the following:

// =====
// Object-based where the key is the role name
// -----

// Example:
const accessList = {
  "Admin": [ "/api/..", "/api/.." ],
  "Data Entry Operator": [ "/api/..", "/api/.." ]
}

// Accessing:
const endpoints = accessList.Admin;
const endpoints = accessList["Data Entry Operator"];

// =====
// Array based where the role name and access points are properties
// -----

// Example:
const accessList = [
  { "Name": "Admin", "Endpoints": [ "/api/.." ] },
  { "Name": "Data Entry Operator", "Endpoints": [ "/api/.."] }
]

// Accessing:
const admin = accessList.filter(x => x.Name == "Admin")[0];
const endpoints = admin.Endpoints;
