User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160611004009
Steps to reproduce:
Run the following script:
let a={};
for(const x in a){}
Actual results:
SyntaxError: missing = in const declaration
Expected results:
Declaring x as const should not have raised a syntax error. http://www.ecma-international.org/ecma-262/6.0/#sec-iteration-statements suggests that a const declaration is valid, and the syntax does not raise an error in Chrome 51.0.2704.84
