JavaScript Questions

The 'else if' statement allows you to check multiple conditions sequentially. If the preceding 'if' or 'else if' conditions are false, the code block associated with the first true 'else if' condition is executed.

Since 'x' is initially 5, the condition 'x > 10' is false. Therefore, the code block under the 'else' statement is executed, setting 'x' to 0.

The typeof operator returns a string representing the data type of its operand, such as 'string', 'number', 'boolean', 'object', 'undefined', etc. It's useful for understanding the nature of variables and expressions in your code.

In JavaScript, the 'string' data type is specifically designed to store and manipulate textual data, representing sequences of characters.

The 'break' statement is crucial in a 'switch' statement. Without it, the code execution would fall through to the next case even if the current case matches. 'break' ensures that only the matching case's code is executed.

length is a property of arrays, not a method. You access it as array.length, not array.length().

Caught errors in JavaScript are typically Error objects. The error.message property provides a descriptive message about the error.

You can access object properties using dot notation (object.property) or bracket notation (object['property']).

The 'while' loop will continue to execute as long as the condition 'i < 5' is true. In each iteration, the value of 'i' is printed and then incremented by 1. The loop stops when 'i' becomes 5.

The value property of an input element (like a text field) stores the current value entered by the user.
