The element is implicitly declared as having an 'any' type due to the fact that an expression of type 'any' cannot be utilized to index type '{}'

I have a variable initialized with properties like this:

const decoded = JSON.parse(nk.binaryToString(message.data));

const matchStateChanges = {
  humans: {},
  ball: {},
}

const { name } = decoded // for example, a string like "Player1"
matchStateChanges.humans[name] = state.humans[name] // an object type like {pos: {12,13}}

However, the compiler is throwing this error:

$ npx tsc

match_control.ts:145:7 - error TS7053: Element implicitly has an 'any' type because expression of type 'any' can't be used to index type '{}'. 145 matchStateChanges.humans[name] = state.humans[name] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

What am I missing here?

Answer №1

Success!:

// Defining a custom interface to uniquely type the object
interface EntityObject {
  [index: string]: object
}

..

const entities: EntityObject = {}

// Continuously update this as we iterate through messages to only send relevant changes
const stateChanges = {
  entities,
  ball: {},
}
