Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the nextTick function from Vue.

Vue

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Importing unrelated functions like useState or watch.

Forgetting to import nextTick before using it.

The nextTick function is imported from Vue to schedule DOM updates after reactive data changes.

2fill in blank

medium

Complete the code to use nextTick to wait for DOM update after changing a reactive variable.

Vue

count.value++;
[1](() => {
  console.log('DOM updated');
});

Drag options to blanks, or click blank then click option'

Awatch

BonMounted

CnextTick

DsetTimeout

💡 Hint

Common Mistakes

Using setTimeout instead of nextTick, which is less reliable.

Using watch or onMounted which serve different purposes.

Using nextTick ensures the callback runs after Vue updates the DOM following reactive changes.

3fill in blank

hard

Fix the error in the code by filling the blank with the correct way to await nextTick.

Vue

async function update() {
  count.value++;
  await [1]();
  console.log('DOM updated');
}

Drag options to blanks, or click blank then click option'

BsetTimeout

CwatchEffect

DonUpdated

💡 Hint

Common Mistakes

Using setTimeout which does not guarantee DOM update timing.

Using watchEffect or onUpdated which are lifecycle or reactive watchers.

Awaiting nextTick() pauses the async function until the DOM updates after reactive changes.

4fill in blank

hard

Fill both blanks to create a reactive variable and update it, then wait for DOM update using nextTick.

Vue

const count = [1](0);

count.value++;
await [2]();

Drag options to blanks, or click blank then click option'

Aref

CnextTick

Dwatch

💡 Hint

Common Mistakes

Using reactive instead of ref for a single primitive value.

Forgetting to await nextTick after changing reactive data.

ref creates a reactive variable holding a value. nextTick waits for DOM update after changing it.

5fill in blank

hard

Fill all three blanks to import, create a reactive variable, and use nextTick to wait for DOM update after increment.

Vue

import { [1], [2] } from 'vue';

const count = [3](0);

count.value++;
await nextTick();

Drag options to blanks, or click blank then click option'

BnextTick

Creactive

Dwatch

💡 Hint

Common Mistakes

Importing reactive instead of ref for primitive reactive data.

Not importing nextTick or mixing up imports.

Using reactive instead of ref to create count.

Import ref and nextTick from Vue. Use ref to create a reactive variable. Then increment and await DOM update.
