The console.countReset() static method resets counter used with {{domxref("console/count_static", "console.count()")}}.

Syntax

js-nolint
console.countReset()
console.countReset(label)

Parameters

  • label {{optional_inline}}
    • : 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 ({{jsxref("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:

plain
"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:

plain
"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.
