fromPairs

INFO

This function is only available in es-toolkit/compat for compatibility reasons. It either has alternative native JavaScript APIs or isn’t fully optimized yet.

When imported from es-toolkit/compat, it behaves exactly like lodash and provides the same functionalities, as detailed here.

Convert a two-dimensional array or Map into an object.

Signature

function fromPairs<T extends string | number | symbol, U>(data: Array<[T, U]> | Map<T, U>): { [key in T]: U };

Parameters

• data (Array<[T, U]> | Map<T, U>): The two-dimensional array or Map to be converted. Each sub-array in the two-dimensional array should have two elements, with the first element as the key and the second as the value.

Returns

({ [key in T]: U }): The converted object with the same keys and values as the input parameters.

Examples

const data = [
  ['a', 1],
  ['b', 2],
  ['c', 3],
];
const result = fromPairs(data);
// result will be { a: 1, b: 2, c: 3 }
