console: countReset() static method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Note: This feature is available in Web Workers.

The console.countReset() static method resets counter used with console.count().

Syntax

js
console.countReset()
console.countReset(label)

Parameters

label Optional

A string. If supplied, countReset() resets the count for that label to 0. If omitted, countReset() resets the default counter to 0.

Return value

None (undefined).

Examples

For example, given code like this:

js
function greet(user) {
  console.count();
  return `hi ${user}`;
}

greet("bob");
greet("alice");
greet("alice");
console.count();
console.countReset();

Console output will look something like this:

"default: 1"
"default: 2"
"default: 3"
"default: 4"
"default: 0"

Note that the call to console.counterReset() resets the value of the default counter to zero.

If we pass the user variable as the label argument with the string "bob" to the first invocation of console.count(), and the string "alice" to the second:

js
function greet(user) {
  console.count(user);
  return `hi ${user}`;
}

greet("bob");
greet("alice");
greet("alice");
console.countReset("bob");
console.count("alice");

We will see output like this:

"bob: 1"
"alice: 1"
"alice: 2"
"bob: 0"
"alice: 3"

Resetting the value of the counter "bob" only changes the value of that counter. The value of "alice" is unchanged.
