RangeError

The RangeError object indicates an error when a value is not in the set or range of allowed values.

Description

A RangeError is thrown when trying to pass a value as an argument to a function that does not allow a range that includes the value.

This can be encountered when:

passing a value that is not one of the allowed string values to String.prototype.normalize(), or
when attempting to create an array of an illegal length with the Array constructor, or
when passing bad values to the numeric methods Number.prototype.toExponential(), Number.prototype.toFixed() or Number.prototype.toPrecision().

Constructor

Examples

Using RangeError (for numeric values)

function check(n)
{
    if( !(n >= -500 && n <= 500) )
    {
        throw new RangeError("The argument must be between -500 and 500.")
    }
}

try
{
    check(2000)
}
catch(error)
{
    if (error instanceof RangeError)
    {
        // Handle the error
    }
}

Using RangeError (for non-numeric values)

function check(value)
{
    if(["apple", "banana", "carrot"].includes(value) === false)
    {
        throw new RangeError('The argument must be an "apple", "banana", or "carrot".')
    }
}

try
{
    check("cabbage")
}
catch(error)
{
    if(error instanceof RangeError)
    {
        // Handle the error
    }
}
