💡 Numeric Separator in Js

The Numeric Separator in JavaScript is a feature introduced in ECMAScript 2021 (ES12) to improve the readability of large numeric literals. By using underscores (_) as visual separators, developers can format numbers in a way that makes them easier to understand at a glance without affecting their value.

Purpose
The primary goal of the numeric separator is to enhance the clarity of numbers, especially when dealing with large values, such as monetary amounts, precise measurements, or binary and hexadecimal codes.

Features
Improves Readability: Numbers can be grouped similarly to how commas or spaces are used in written numerals (e.g., 1,000,000 or 1 000 000). For instance, 1_000_000 is much easier to read than 1000000.

Supports Various Numeric Formats: It can be used in decimal, hexadecimal, binary, and octal number systems.

Purely Visual: The underscores do not impact how the number is stored or used in calculations. They are strictly for the developer's benefit.

Restrictions
Numeric separators cannot appear at the start or end of a number.
They cannot directly follow or precede a decimal point, or appear next to an exponent symbol (e or E).
