I'm new to js, I see this a lot in the code I'm reading
_.pick(req.body, ' ' , ' ')
What does req.body do? And when can I say req.body.something?

The req. body object allows you to access data in a string or JSON object from the client side. You generally use the req. body object to receive data through POST and PUT requests in the Express server.
Express has a built-in express. json() function that returns an Express middleware function that parses JSON HTTP request bodies into JavaScript objects. The json() middleware adds a body property to the Express request req . To access the parsed request body, use req.
No need to install body-parser with express , but you have to use it if you will receive post request.
req.body holds parameters that are sent up from the client as part of a POST request. See the API.
// POST user[name]=tobi&user[email][email protected]
req.body.user.name
// => "tobi"
req.body.user.email
// => "[email protected]"
// POST { "name": "tobi" }
req.body.name
// => "tobi"
(req.body, ' ' , ' ') --> here req is the parameter of your function and using this parameter your can access the properties over then url.
so look this example
suppose this is form
<form>
enter the name : <input type="text" name="name">
<button type ="submit"> submit </button>
</form>
so if you want to access the name -- which is filled by the user end.
so for this you can
do like this-> console.log(req.body.name); -- this will print the name (property) in console.
