# zipObject
Combines two arrays, one of property names and one of corresponding values, into a single object.
This function takes two arrays: one containing property names and another containing corresponding values. It returns a new object where the property names from the first array are keys, and the corresponding elements from the second array are values. If the `keys` array is longer than the `values` array, the remaining keys will have `undefined` as their values.
## Signature
```typescript
function zipObject<P extends string | number | symbol, V>(keys: P[], values: V[]): { [K in P]: V };
```
### Parameters
- `keys` (`P[]`): An array of property names.
- `values` (`V[]`): An array of values corresponding to the property names.
### Returns
(`{ [K in P]: V }`): A new object composed of the given property names and values.
## Examples
```typescript
const keys = ['a', 'b', 'c'];
const values = [1, 2, 3];
const result = zipObject(keys, values);
// result will be { a: 1, b: 2, c: 3 }
const keys2 = ['a', 'b', 'c'];
const values2 = [1, 2];
const result2 = zipObject(keys2, values2);
// result2 will be { a: 1, b: 2, c: undefined }
const keys3 = ['a', 'b'];
const values3 = [1, 2, 3];
const result3 = zipObject(keys3, values3);
// result3 will be { a: 1, b: 2 }
```
