console: countReset() method
The console.countReset()
method resets counter used with
console.count()
.
Note: This feature is available in Web Workers
Syntax
js
countReset()
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
let user = "";
function greet() {
console.count();
return `hi ${user}`;
}
user = "bob";
greet();
user = "alice";
greet();
greet();
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 count()
, and the string "alice" to
the second:
js
let user = "";
function greet() {
console.count(user);
return `hi ${user}`;
}
user = "bob";
greet();
user = "alice";
greet();
greet();
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.
