Code Inspections in Vue

Inspection	Description	Default Severity
Data function	This inspection warns if data property of Vue component is not a function. When defining a component, `data` must be declared as a function that returns the initial data object, because there will be many instances created using the same definition. If we still use a plain object for `data`, that same object will be shared by reference across all instances created! By providing a `data` function, every time a new instance is created, we can simply call it to return a fresh copy of the initial data.	Warning
Duplicate template/script tag	This inspection warns if there is more than one `template` or `script` tag in Vue file. Vue Component specification indicates that each *.vue file can contain at most one `template` or `script` block at a time.	Warning
