 ### Step 2: Call VK API Methods
 You can use method **api** for call api methods.
-```nodejs
+```node
 const userObject = vk.api("users.get", {
 	user_ids : [1].join(",")
 }); // [{ id : 1, first_name : "Pavel", last_name : "Durov" }]
 ```
 ### Additional tools
 You can use method **exec** for call api method **Execute**.
-```nodejs
+```node
 const vkScript = `var userObject = API.users.get({"user_ids":[1]});
 
 return userObject[0];`;
 const userObject = vk.exec(vkScript); // { id : 1, first_name : "Pavel", last_name : "Durov" }
 ```
 And you can use additional tool for upload doc into server. Use method **uploadDoc** *(method at beta-develop)*  
-```nodejs
+```node
 const fs = require('fs');
 
 const filename = "picture.png";
