I read about the yield keyword in JavaScript and I need to use it in my project. I read that this keyword has been implemented starting from a certain version of JS so I think that old browsers don't support it (right?).
Is there a way to check if the yield keyword is supported? or at least is there a way to check if the version of JS is greater or equal than the one that implements that keyword (1.7)?
Here's a function for checking if yield can be used.
var can_yield = (function(){
try {
return eval("!!Function('yield true;')().next()");
}
catch(e) {
return false;
}
})();
