[amp_mcq option1=”throw” option2=”try” option3=”catch” option4=”scope” correct=”option3″]
The correct answer is: C. catch
A try block is used to try to execute a block of code. If an error occurs, the code inside the catch block is executed. The throw statement is used to throw an error. The scope keyword is used to define the scope of a variable.
Here is an example of how to use a try–catch block to handle errors:
try {
// This code may throw an error.
} catch (error) {
// Handle the error.
}
In this example, if the code inside the try block throws an error, the code inside the catch block will be executed. The catch block can be used to handle any type of error.
Here is an example of how to use a throw statement to throw an error:
throw new Error("This is an error");
In this example, the throw statement will throw an error with the message “This is an error”. The error will be caught by any catch blocks that are defined in the current scope.
