Adobe Exam AD0-E720 Topic 8 Question 29 Discussion

Actual exam question for Adobe's AD0-E720 exam

Question #: 29
Topic #: 8

An Adobe commerce developer wants to initialize a JavaScript component using a data attribute. Which option would initialize the JavaScript component?

A<nav data-bind='{'<component_name>': {...}}'></nav>

B<nav data-init='{'<component_name>': {...}}'></nav>

C<nav data-mage-init='{'<component_name>': {...}}'></nav>

Show Suggested Answer

Suggested Answer: C

To initialize a JavaScript component using a data attribute, the developer should use the data-mage-init attribute. This attribute allows the developer to specify the name and configuration of the component in a JSON format. For example:

This will initialize the nav component from the Vendor_Module/js/nav file with the given options. The data-bind and data-init attributes are not valid and will not work, as they are not supported by Magento. Reference: [JavaScript initialization], [data-mage-init]

I definitely remember practicing with `data-mage-init`, but I can't recall if it was specifically for JavaScript components or something else.

I'm a bit confused; I thought `data-bind` was used for something else. Is it really the right choice here?

I think I've seen a similar question before, and I believe it was about using `data-mage-init` for initialization.

I remember that data attributes are often used to initialize components, but I'm not sure which one is correct here.

Okay, let me walk through this step-by-step. We want to initialize a JavaScript component, and the question says we should use a data attribute. Looking at the options, A and B don't seem quite right - the syntax doesn't match what I'm familiar with. But C, using `data-mage-init`, that rings a bell. I'm pretty confident that's the correct answer.

Hmm, I'm not totally sure about this one. I know we've covered data attributes for initializing components, but I can't remember the exact syntax. I'll have to think it through carefully.

I think the answer is C. The question specifically mentions initializing a JavaScript component using a data attribute, and the documentation I've seen for Adobe Commerce indicates that the `data-mage-init` attribute is the way to do that.

I'm a bit confused by this question. I know we've covered initializing components with data attributes, but the syntax in these options is not what I'm used to seeing. I'll have to review my notes and the documentation to make sure I understand this properly before answering.
