RangeError: Array length must be a finite positive integer (Edge) RangeError: invalid array length (Firefox) RangeError: Invalid array length (Chrome) RangeError: Invalid array buffer length (Chrome)
Cause of the error: The length of an Array or an ArrayBuffer can only be represented by an unsigned 32-bit integer, which only stores values ranging from 0 to 232-1. While creating an Array or an ArrayBuffer, if the array length is either negative or greater than or equal to 232 then this error occurs.
Example 1: In this example, the length property is set to 6, which is a valid value, therefore no error occurred.
Example 2: In this example, the length property is set to -1, which is an invalid value, therefore the error has occurred.
