if are you using node js you can create or append a string value with " ," operator then inside the loop you can

for (var j = 0; j <= data.legth -1; j++) {
                    lang += data.lang  +", " ;

                }

 var langs = lang.split(',')
 console.log("Languages =>",  lang, typeof(lang), typeof(langs), langs) 
 console.log(lang[0]) // here access arrary by index value
            

you can see the type of string and object
