And for the benefit of anyone arriving at this question now, it's worth pointing out that since the question was answered, all browsers have now implemented the console object, so console.log() etc should work in all browsers, including IE. However, in all cases, you need to have the debugger window open at the time, otherwise calls to con

Right now I just get the message. edit: As many people below have posted, it is possible to get a stack trace for a JavaScript exception but I want to get a stack trace for my exceptions. For example: function javascript print error foo() { bar(2); } function bar(n) { if (n < 2) throw "Oh no! 'n' is too small!" bar(n-1); } When foo is called, I want to get a stack trace which includes the calls to foo, bar, bar. javascript stack-trace share|improve this question edited Mar 11 '09 at 18:58 asked Feb 26 '09 at 18:36 David Wolever 54.4k38207357 Just google for javascript stack trace.

Chrome debugger still needs throw new Error('arrrgh'); as stated, however (but Chrome seems to give much more detailed traces). –user568458 Aug 20 '13 at 12:52 11 @ChetanSastry I googled for 'javascript stack trace' and this was the first result –David Sykes Mar 20 '14 at 13:23 | show 1 more comment 20 An

Syntax Errors Syntax errors, also called parsing errors, occur at compile time in traditional programming languages and at interpret time in JavaScript. For example, the following line causes a syntax error because it is missing a closing parenthesis. When a syntax error occurs in JavaScript, only the code contained within the same thread as the syntax error is affected and the rest of the code in other threads gets executed assuming nothing in them depends on the code containing the error. Runtime Errors Runtime errors, also called exceptions, occur during execution (after compilation/interpretation). For example, the following line causes a runtime error because here the syntax is correct, but at runtime, it is trying to call a method that does not exist. Exceptions also affect the thread in which they occur, allowing other JavaScript threads to continue normal execution. Logical Errors Logic errors can be the most difficult type of errors to track down. These errors are not the result of a syntax or runtime error. Instead, they occur when you make a mistake in the logic that drives your script and you do not get the result you expected. You cannot catch th
