Can the random number of element to be picked in faker.helper.arrayElements() be zero?

[hazem-alabiad]

If I left the count parameter in faker.helper.arrayElements() unset, does the number of elements to be picked be randomly zero?

This is possible in some edge cases:

1. You provide a count parameter of 0
2. You provide a count parameter of less than 0 (the value will get defaulted to 0)

   faker/src/modules/helpers/index.ts

   Lines 455 to 457 in 9432edd

   	} else if (count < 0) {
   	count = 0;
   	}

3. You provide an array parameter an empty array

   faker/src/modules/helpers/index.ts

   Lines 453 to 455 in 9432edd

   	} else if (count > array.length) {
   	count = array.length;
   	} else if (count < 0) {

So in the case, you stated this will not happen, since the count parameter will default to a random value between 1 and the array length

faker/src/modules/helpers/index.ts

Line 452 in 9432edd

: this.faker.datatype.number({ min: 1, max: array.length });
