What is Interpolation?

Interpolation in Vue is used to display dynamic data in the DOM using double curly braces {{ }}.

Basic Syntax

HTMLRead-only

<p>{{ message }}</p>

<p>{{ message }}</p>

Using Expressions

You can use JavaScript expressions inside interpolation.

HTMLRead-only

<p>{{ 5 + 5 }}</p>
<p>{{ message.toUpperCase() }}</p>

<p>{{ 5 + 5 }}</p>
<p>{{ message.toUpperCase() }}</p>

Multiple Interpolations

HTMLRead-only

<p>{{ firstName }} {{ lastName }}</p>

<p>{{ firstName }} {{ lastName }}</p>

Raw HTML (v-html)

Use v-html directive to render raw HTML instead of plain text.

HTMLRead-only

<div v-html="rawHtml"></div>

<div v-html="rawHtml"></div>

Important Notes

Interpolation is only for text content
Cannot be used inside HTML attributes
Supports JavaScript expressions only
Does not support statements like if or loops

Best Practices

Keep expressions simple
Use computed properties for complex logic
Avoid heavy calculations in templates
Use v-html carefully to avoid XSS risks

Common Mistakes

Using interpolation inside attributes
Writing complex logic inside {{ }}
Confusing interpolation with directives
Using v-html without sanitizing data

Conclusion

Interpolation is a core feature of Vue that allows displaying dynamic data easily. It is simple yet powerful when used correctly.
