How to Correctly Access Integer Properties in JavaScript?

Clarifying Single Dot Notation for Integer Properties

When attempting to access a property of an integer using a single dot, you may encounter a syntax error. This occurs because the dot is considered part of the integer itself.

To resolve this issue, there are several alternatives you can use:

• Double Dots: 3..toFixed(5)
• Space: 3 .toFixed(5)
• Parentheses: (3).toFixed(5)
• Bracket Notation: 3["toFixed"](5)

The syntax error arises because the code interprets the single dot notation as (3.)toFixed(5). Since you can't immediately follow a number with an identifier, this results in a syntax error.

Therefore, to successfully access an integer's property, you can use any method that prevents the period from being interpreted as part of the number. Parentheses are often regarded as the clearest way to achieve this: (3).toFixed(5)
