removeDuplicatesByKeyValue

Returns an array of objects where a value of a specific key can only occur once. The first instance of the key/value pair is preserved and subsequent instances are removed. You can optionally pass in a boolean to make detection case sensitive.

TypeScript

function removeDuplicatesByKeyValue<T extends object, U extends keyof T>(
  arr: T[],
  key: U,
  isCaseSensitive = false
)

// Example:

const members = [
    { id: 1, name: "Stephen" },
    { id: 2, name: "Andrea" },
    { id: 1, name: "Monica" },
    { id: 4, name: "Dylan" },
]

removeDuplicatesByKeyValue(members, "id")
//=>
 [
  { id: 1, name: "Stephen" },
  { id: 2, name: "Andrea" },
  { id: 4, name: "Dylan" },
 ]
