how to use the partition function from lodash in javascript

The partition function from lodash allows you to split an array into two groups based on a given condition or predicate function.

Here's an example of how to use the partition function:

index.tsx
const _ = require('lodash');

const numbers = [1, 2, 3, 4, 5, 6];

const [evenNumbers, oddNumbers] = _.partition(numbers, (number) => (number % 2 === 0));

console.log(evenNumbers); // Output: [2, 4, 6]
console.log(oddNumbers); // Output: [1, 3, 5]
249 chars
9 lines

In the above example, we use the partition function from lodash to split the numbers array into two groups - even numbers and odd numbers. We pass a predicate function as the second argument to the partition function. This function returns true for even numbers, which ends up grouping all even numbers in one array and odd numbers in another array.

The partition function returns an array of two arrays in this format - [matchingElementsArray, nonMatchingElementsArray]. In our example, evenNumbers array contains all even numbers from the numbers array and oddNumbers array contains all odd numbers.
