Access JSON key with forward slashes NodeJS

Question

I have an object. In my object, there is a key with forward slashes and I would like to access the child of the key with forward slashes pattern

I have tried several approaches to no avail, please help with a solution to access the pattern property. Object is at the bottom

test.attributes./worker/workAssignment/homeOrganizationalUnits/typeCode/codeValue


SyntaxError: Unexpected token /

key = '/worker/workAssignment/homeOrganizationalUnits/typeCode/codeValue'
test.attributes.key


undefined

test.attributes.["key"]

Thrown:
SyntaxError: Unexpected token [

test.attributes.\/worker\/workAssignment\/homeOrganizationalUnits\/typeCode\/codeValue

Thrown:
SyntaxError: Invalid or unexpected token

{
    "attributes": {
        "/worker/workAssignment/homeOrganizationalUnits/typeCode/codeValue": {
            "pattern": "Department"
        }
    },
    "value": {
        "links": [{
            "href": "/codelists/hr/v3/worker-management/departments/WFN/1?$filter=foreignKey eq {payrollGroupCode}",
            "mediaType": "application/json",
            "method": "GET"
        }]
    }
}

Sorry Chris, I don't think that is correct: `SyntaxError: Unexpected token [` — Goldfish, May 09 '19 at 20:23
Works fine: https://jsfiddle.net/khrismuc/ex3Lwyqr/ (no dot before the square brackets) — , May 09 '19 at 20:24
Ah apologies, the key is to remove the `.` before referencing the variable in brackets. JS 101 — Goldfish, May 09 '19 at 20:25

Either test.attributes[ key ] or test.attributes["/worker/workAssignment/homeOrganizationalUnits/typeCode/codeValue"], both are fine.

You can use the '/' character in the key name for object access as long as it is the value of a variable you use for the lookup.

var key = '///';
var obj = { '///': 'foo' };
obj[key];

> 'foo'
