Breakpoint :-

breakpoint will stop executing, and let you examine JavaScript values.

After examining values, you can resume the execution of code (typically with a play button).

Debugger :-

The debugger; stops the execution of JavaScript, and callsthe debugging function.

The debugger statement suspends execution, but it does not close any files or clear any variables.

Example:-
function checkBuggyStuff() {
  debugger; // do buggy stuff to examine.
};

debugger is a reserved keyword by EcmaScript and given optional semantics since ES5

Error: User Rate Limit ExceededError: User Rate Limit Exceedednode debug myscript.js.

Error: User Rate Limit ExceededError: User Rate Limit Exceeded:

Syntax

DebuggerStatement :
    debugger ;

Semantics

Evaluating the DebuggerStatement production may allow an implementation to cause a breakpoint when run under a debugger. If a debugger is not present or active this statement has no observable effect.

The production DebuggerStatement : debugger ; is evaluated as follows:

  1. If an implementation defined debugging facility is available and enabled, then
    1. Perform an implementation defined debugging action.
    2. Let result be an implementation defined Completion value.
  2. Else
    1. Let result be (normal, empty, empty).
  3. Return result.

  1. Using console.log() to print out the values in the browser console. (This will help you understand the values at certain points of your code)

  2. Debugger keyword. Add debugger; to the locations you want to debug, and open the browser's developer console and navigate to the sources tab.
