Difference between using subscript syntax and “dot” syntax when accessing attributes of a variable or advantages of usage one of them

Question

When to use

{{ variable.property }}

and when to use

{{ variable['property'] }}

Is there a difference between these methods of accessing attributes of a variable or advantages of using one of them?

Answer 1

They're both the same for the most part.

The only time I'd use the second way you listed is when the property is a variable.

For instance:

{% set foo = 'name' %}
{{ variable[foo] }}

This will give you {{ variable.name }}

Answer 2

Generally speaking, no. They are just two ways of saying the same thing.

Dot syntax is necessary when you are referring to a method within an object. However, if you are only trying to access the property of an object (or a value within an array), either technique will work.
