How can I determine the current line number in JavaScript?

Does JavaScript have a mechanism for determining the line number of the currently executing statement (and if so, what is it)?

Solution 1:

var thisline = new Error().lineNumber

If that doesn't work in whatever environment you're using, you can try:

var stack = new Error().stack

Then hunt through the stack for the line number.

You can use:

function test(){
    console.trace();
}

test();
