Converting Array Access to Dot Notation in JavaScript

In JavaScript, accessing properties of objects can be done using either bracket notation or dot notation. While bracket notation is useful in certain scenarios, dot notation often provides better readability and simplicity.

For example, consider the following code snippet where array access is used:

To convert this access method to dot notation, if the property name is a valid JavaScript identifier (i.e., it does not contain any spaces or special characters and does not start with a number), you can simply replace the square brackets with a dot:

Why Convert to Dot Notation?

Using dot notation has several advantages:

Readability: Dot notation is generally easier to read and understand at a glance.

Error Reduction: It minimizes the risk of introducing errors due to typos or malformed strings.

Consistency: Promotes a more consistent coding style across your codebase.

When to Use Bracket Notation?

Bracket notation is still essential in scenarios where:

Dynamic Property Names: When the property names are generated dynamically.

Invalid Identifiers: If the property names contain characters that are not valid JavaScript identifiers.

For example, if the property name is stored in a variable or includes special characters:
