Possible Duplicate: jQuery uses (new Function(“return ” + data))(); instead of eval(data); to parse JSON, why? Given a string which represents a valid JSON string , is there a difference between these two parsing methods: var str, obj; str = '{"prop":"value"}'; // method 1: obj = eval( '(' + str + ')' ); // method 2: obj = ( new Function( 'return (' + str + ');' ) )(); I noticed that jQuery uses the second method to parse JSON strings (in environments that lack a built-in JSON parser). I wonder why they don't use the first method. Why create a function object and invoke it when you can just use eval() ? Please close as exact duplicate
