This post is part of my Today I learned series in which I share all my learnings regarding web development.

Today I saw an update to the MDN compat data, and it covered a method available on console. console includes many more useful functions than the commonly used console.log method.

One of them is console.trace that you can use to log JavaScript stack traces.

function someFunction() {
  function anotherFunction() {
    console.trace();
  }

  anotherFunction();
}

somefunction();

// logs:
// anotherFunction @ VM3917:3
// someFunction    @ VM3917:6
// (anonymous)     @ VM4184:1

One thing I learned is that console.trace also accepts multiple arguments so that you can log objects and stack traces in the same call. 🎉

function someFunction() {
  function anotherFunction() {
    console.trace({foo: "bar"});
  }

  anotherFunction();
}

somefunction();

// logs:
// { foo: "bar" }
// anotherFunction @ VM3917:3
// someFunction    @ VM3917:6
// (anonymous)     @ VM4184:1

If you want to see it in action, here's a quick video. 👇
