The index parameter represents the value that you want to check if it
falls within a specified range.
The min parameter represents the minimum value that the index should be
compared against in the rangeCheck function.
The max parameter in the rangeCheck function represents the maximum value
that the index parameter is allowed to have. If the index is greater than this max value, a
RangeError will be thrown.
Optionalmessage: string = 'Index out of bounds.'The message parameter is a string that represents the
error message to be thrown if the index is out of bounds. By default, if no message is provided when
calling the rangeCheck function, the message "Index out of bounds." will be used.
The
rangeCheckfunction in TypeScript is used to validate if an index is within a specified range and throws aRangeErrorwith a custom message if it is out of bounds.
