// input.js for ( var { x = 0 in [ 0 ] } of [ 0 ] ); _____________________ Hello, Executing the input.js using JSC throws SyntaxError, but it is expected to terminate normally. Running the input.js with JSC gives --- $ jsc input.js Exception: SyntaxError: Unexpected keyword 'in'. Expected either a closing '}' or an ',' after a property destructuring pattern. at input.js:1 --- while other engines behave like --- # V8 $ node input.js // no error # GraalJS $ js input.js // no error --- WebKit version: 615.1.10
