Examples
EvalError
is not used in the current ECMAScript specification and will thus not be thrown by the runtime. However, the object itself remains for backwards compatibility with earlier versions of the specification.
Creating an EvalError
try { throw new EvalError('Hello', 'someFile.js', 10); } catch (e) { console.log(e instanceof EvalError); // true console.log(e.message); // "Hello" console.log(e.name); // "EvalError" console.log(e.fileName); // "someFile.js" console.log(e.lineNumber); // 10 console.log(e.columnNumber); // 0 console.log(e.stack); // "@Scratchpad/2:2:9\n" }
