Evaluated skills

  • Create reusable components in Vue.js
  • Question 1

    If you want to pass data down to a child component, which technique should you use?

    • Computed properties

    • Methods

    • Props

    • Data store

  • Question 2

    There is currently a bug in the app where a component is showing different data types in the message such as arrays and objects.

    <p>{{ message }}</p>
    export default {
    props: ['message']

    What is the best way to prevent this bug from occurring?

    • Define the  required  property on the prop.


    • Define the type property with a value of  String.


    • Set a default data property on the prop.

    • Define a custom prop name that tells other developers to only use strings.

  • Question 3

    A developer is trying to use SCSS techniques in the following block of code.

    <div class="form-wrapper">
    <label class="form-label">Form Label</label>
    <input class="form-input" type="text" />
    .form {
    &-wrapper { margin: 25px 0; }
    &-label { font-size: 1.2rem; }
    &-input { padding: 10px 5px; }

    What are they doing wrong?

    • They need to add the scss attribute to the <style> block.


    • They need to add the lang="scss" attribute to the <style> block.


    • They need to wrap the styles in <scss> block.


    • They need to add preprocessor="scss" attribute to the <style> block.
