Q

Which statement accurately describes the behavior of console.log() in JavaScript?

A). It halts script execution until the log is displayed. B). It continues script execution while logging to the console. C). It executes in parallel with other statements in the script. D). It pauses script execution while logging to the console.

Answer & Solution

Answer: Option Option B

Solution:

The behavior of console.log() in JavaScript is that it continues script execution while logging to the console. Unlike some other methods like alert() that can pause script execution until dismissed by the user, console.log() does not interrupt the script flow and allows code to continue executing while logging information to the console. This behavior is beneficial for real-time monitoring, debugging, and tracking variables without disrupting the script's execution flow. It is important to note that console.log() statements do not halt or pause script execution, making them ideal for non-intrusive logging during runtime.
