RangeError() constructor
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The RangeError()
constructor creates RangeError
objects.
Syntax
js
new RangeError()
new RangeError(message)
new RangeError(message, options)
new RangeError(message, fileName)
new RangeError(message, fileName, lineNumber)
RangeError()
RangeError(message)
RangeError(message, options)
RangeError(message, fileName)
RangeError(message, fileName, lineNumber)
Note: RangeError()
can be called with or without new
. Both create a new RangeError
instance.
Parameters
message
Optional-
Human-readable description of the error.
options
Optional-
An object that has the following properties:
cause
Optional-
A property indicating the specific cause of the error. When catching and re-throwing an error with a more-specific or useful error message, this property can be used to pass the original error.
fileName
Optional Non-standard-
The name of the file containing the code that caused the exception
lineNumber
Optional Non-standard-
The line number of the code that caused the exception
Examples
Using RangeError (for numeric values)
js
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)
js
function check(value) {
if (!["apple", "banana", "carrot"].includes(value)) {
throw new RangeError(
'The argument must be an "apple", "banana", or "carrot".',
);
}
}
try {
check("cabbage");
} catch (error) {
if (error instanceof RangeError) {
// Handle the error
}
}
