Summary JSON.parse throws incorrect exception when called w/o arguments
Alexey Shvayka
Reported 2019-06-05 11:19:48 PDT
Test case: JSON.parse() Expected: SyntaxError: JSON Parse error: Unexpected identifier "undefined" Actual: Error: JSON.parse requires at least one parameter ECMA-262: https://tc39.github.io/ecma262/#sec-json.parse No matter how many arguments are passed, `JSON.parse` always coerces first arg to string (step 1) and attempts to parse it (step 2). Other browsers throw SyntaxError.
