TypeTags .SyntaxError

Overview

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.

️🚫

Since error objects do not have unique type tags, a SyntaxError type tag is the same as any other Error object. If you need to check if an error is an instance of a SyntaxError, use instanceof instead.

Usage

import { TypeTags } from 'typetags'


try {
  throw new SyntaxError('Hello', 'someFile.js', 10)
} catch (e) {
  console.error(e instanceof SyntaxError) // true
  console.error(e.message) // Hello
  console.error(e.name) // SyntaxError
  console.error(e.fileName) // someFile.js
  console.error(e.lineNumber) // 10
  console.error(e.columnNumber) // 0
  console.error(e.stack) // @debugger eval code:3:9
}


console.log(TypeTags.SyntaxError)
// → [object Error]
