That’s all we can say right now.
Description
In JavaScript, there are two ways to access the properties of an object:
- dot-notation
(object.property)( Recommended ) - square-bracket notation
(object["property"])( Bad Practice )
The dot notation is preferred because it is easier to read, less verbose, and works better with aggressive JavaScript minimizers.
Bad Practice
const x = object["property"];
Recommended
const x = object.property;
x = object[y];
