Convert Array of single dynamic-key objects into a single object representing all dynamic key entries

Assuming we have the following array structure of n length:

const sourceArray = [
  { "dynamicKey1": true },
  { "dynamicKey2": false },
  { "dynamicKey3": true },
  ...
]

How could I tersely reduce this array to a single object of dynamic length:

const convertedObj = {
  "dynamicKey1": true,
  "dynamicKey2": false,
  "dynamicKey3": true
  ...
}

Thanks!
