Question

What is wrong with this piece of code?

javascript
Copy code
Items.where('quantity').gte(100).lte(150).limit(50).function (err, docs) {// Do something with Docs};
Option 1:
The where method is not used correctly.

Option 2:
The limit is not applied correctly.

Option 3:
There is a syntax error in the function keyword.

Option 4:
The gte and lte conditions are not valid.

Answer 1

The code contains a syntax error with the use of the 'function' keyword. It should be part of an anonymous function passed as a callback, not preceded by a period. So, the best option is 3, There is a syntax error in the function keyword.

Step-by-step explanation:

The problem with the code lies in Option 3: There is a syntax error in the function keyword.

The error is that the keyword function should not be preceded directly by a period. Instead, it should be used with the correct syntax to define an anonymous function that is passed as a callback.

The corrected line of code should have an anonymous function passed as an argument to the method chain without the period before the keyword function.

Correct Syntax:

Items.where('quantity').gte(100).lte(150).limit(50).exec(function (err, docs) {

// Do something with Docs });

In addition, although not explicitly mentioned as an error in the provided options, the use of the execl () method is necessary to execute the query and pass the result to the callback function.

So, the best option is 3, There is a syntax error in the function keyword.
