How Do I Access Properties of an Integer in JavaScript?

Accessing Properties of an Integer

While attempting to access a property of an integer using a single dot, a syntax error occurs. This is due to the period being interpreted as part of the number, resulting in an attempt to follow the number with an identifier immediately.

Alternative Solutions

To avoid this error, you can separate the period from the number using any of the following methods:

• Double dots: 3..toFixed(5)
• Space: 3 .toFixed(5)
• Parentheses: (3).toFixed(5)
• Bracket notation: 3["toFixed"](5)

Recommended Method

Among these alternatives, the most straightforward and recommended method is to enclose the integer in parentheses:

(3).toFixed(5)

This clearly separates the period from the number, preventing any ambiguity in interpretation.
