When JavaScript hits a breakpoint during execution, it stops executing to allow examination of current values, which is why that choice is correct. Breakpoints are essential debugging tools that developers set in their code using the browser's developer tools. When the JavaScript engine reaches a breakpoint, execution halts at that specific line of code. This pause allows developers to inspect the state of variables, the call stack, and any other context necessary to understand the program's behavior at that moment. This examination is crucial for identifying issues or understanding how the code is functioning.

The other options describe behaviors that do not accurately reflect what occurs at a breakpoint. For instance, when JavaScript hits a breakpoint, it does not continue execution; rather, it halts. Skipping subsequent lines of code does not happen at a breakpoint; the code stops there, giving the opportunity for examination, rather than skipping ahead or bypassing sections. Logging errors to the console is also not an automatic feature of breakpoints; errors need to be explicitly captured or logged in the code itself for them to appear in the console. Thus, the function of breakpoints centers around pausing for investigation, making the notion of stopping for examination the central purpose of encountering a breakpoint.
