The SyntaxError object represents an error when trying to interpret syntactically invalid code. It is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.
SyntaxError is a serializable object, so it can be cloned with structuredClone() or copied between Workers using postMessage().
SyntaxError is a subclass of Error.
SyntaxError()
Creates a new SyntaxError object.
Also inherits instance properties from its parent Error.
These properties are defined on SyntaxError.prototype and shared by all SyntaxError instances.
SyntaxError.prototype.constructor
The constructor function that created the instance object. For SyntaxError instances, the initial value is the SyntaxError constructor.
SyntaxError.prototype.name
Represents the name for the type of error. For SyntaxError.prototype.name, the initial value is "SyntaxError".
Inherits instance methods from its parent Error.
try {
eval("hoo bar");
} catch (e) {
console.log(e instanceof SyntaxError); // true
console.log(e.message);
console.log(e.name); // "SyntaxError"
console.log(e.stack); // Stack of the error
}
try {
throw new SyntaxError("Hello");
} catch (e) {
console.log(e instanceof SyntaxError); // true
console.log(e.message); // "Hello"
console.log(e.name); // "SyntaxError"
console.log(e.stack); // Stack of the error
}
