Tricky JavaScript Interview Questions | #0112 #javascript

Welcome to Coding Frontier,
In this video, the function foo() is expected to return an object containing a message. However, due to the way JavaScript handles line breaks, it actually returns undefined. This happens because there’s an unintended line break after the return statement. In JavaScript, when return is followed by a line break, the interpreter automatically inserts a semicolon, effectively making the statement return;. As a result, the object { message: “Hello” } is never returned, and console.log(foo()) outputs undefined. To fix this, place the opening brace on the same line as return, like this: return { message: “Hello” };.
