+/**
+* Creates an array of elements split into two groups, the first of which contains elements
+* `predicate` returns truthy for, the second of which contains elements
+* `predicate` returns falsy for. The predicate is invoked with one argument: (value).
+*
+* @template T
+* @param source - The array or object to iterate over.
+* @param [predicate=identity] - The function invoked per iteration.
+* @returns Returns the array of grouped elements.
+*
+* @example
+* partition([{ a: 1 }, { a: 2 }, { b: 1 }], 'a');
+* // => [[{ a: 1 }, { a: 2 }], [{ b: 1 }]]
+*
+* partition([{ a: 1 }, { a: 2 }, { b: 1 }], { b: 1 });
+* // => [[{ b: 1 }], [{ a: 1 }, { a: 2 }]]
+*
+* partition({ item1: { a: 0, b: true }, item2: { a: 1, b: true }, item3: { a: 2, b: false }}, { b: false })
+* // => [[{ a: 2, b: false }], [{ a: 0, b: true }, { a: 1, b: true }]]
+*
+* partition([{ a: 1 }, { a: 2 }, { a: 3 }], ['a', 2]);
+* // => [[{ a: 2 }], [{ a: 1 }, { a: 3 }]]
