Konsole tyd()

Voorbeeld

Die tyd wat dit neem om 'n for-lus 100 000 keer te laat loop:

console.time();
for (let i = 0; i < 100000; i++) {
  // some code
}
console.timeEnd();

Meer voorbeelde hieronder.


Definisie en gebruik

Die time()metode begin 'n timer in die konsole-aansig.

Die time()metode laat jou toe om tydkode vir toetsdoeleindes.

Let wel

Jy kan baie timers op dieselfde tyd laat loop.

Gebruik die etiketparameter om verskillende tydtellers te benoem.

Sien ook:

Die console.timeEnd()-metode .


Sintaksis

console.time(label)

Grense

Parameter Description
label Optional.
A label to give the timer a name.


Meer voorbeelde

Gebruik die etiket parameter:

console.time("test1");
for (let i = 0; i < 100000; i++) {
  // some code
}
console.timeEnd("test1");

Wat is die vinnigste, die for-lus of die while-lus?

console.time("for loop");
for (let i = 0; i < 1000000; i++) {
  // some code
}
console.timeEnd("for loop");

let i = 0;
console.time("while loop");
while (i < 1000000) {
  i++
}
console.timeEnd("while loop");
