Convert an array of object into 2-dimensional array to group the elements with same id in typescript

I have an array of object as

arr1 = [{catid: 1, name: 'mango', category: 'fruit'}, {catid: 2 name: 'potato', category: 'veg'}, {catid: 3, name: 'chiken', category: 'nonveg'},{catid: 1, name: 'apple', category: 'fruit'}, {catid: 1, name: 'banana', category: 'fruit'}];

I want to convert the above array to 2-d array based on catid of the element(basically want to group all elements on the basis of same catid):

arr2 = [[{catid: 1, name: 'mango', category: 'fruit'},{catid: 1, name: 'apple', category: 'fruit'}, {catid: 1, name: 'banana', category: 'fruit'} ],[{catid: 2 name: 'potato', category: 'veg'}],[{catid: 3, name: 'chiken', category: 'nonveg'}]]

How can I do this in typescript or javascript.
