A RangeError exception is thrown when a numeric value is outside the acceptable range. When working with arrays, referring to an index position of an array item that does not exist will throw a RangeError exception. Using
Number.toExponential()
,
Number.toPrecision()
, and
Number.toFixed()
methods will throw a RangeError exception in cases where the arguments are outside the acceptable range of numbers. You can extend
Number.toExponential()
,
Number.toPrecision()
, and
Number.toFixed()
to avoid throwing a RangeError.
Other situations that cause this exception to be thrown include the following:
