About this method
Check if an index exists or not.
You can initialize an index with any name.
The index is created on Algolia’s servers when you add objects or set settings.
To prevent accidentally creating new indices, or changing existing indices,
you can use the exists
method.
The exists
method returns a boolean that indicates whether an initialized index has been created.
Be careful when using this method to execute code conditionally.
Because index operations are asynchronous, an index might not yet exist when you call the exist
method, but it might exist when the conditional code runs.
Be mindful of the surrounding code, and of any process that might change your indices.
Examples

Parameters
This method doesn't take any parameters.
Response
This section shows the JSON response returned by the API.
Each API client encapsulates this response inside objects specific to the programming language,
so that the actual response might be different.
You can view the response by using the getLogs
method.
Don’t rely on the order of attributes in the response, as JSON doesn’t guarantee the ordering of keys in objects.
JSON format
This method returns true
if the index exists, and false
otherwise.
