How to Declare a Long Integer in JavaScript?

Estimated read time 1 min read

In JavaScript, all numbers are treated as floating-point numbers, but you can store large integers as well. There is no specific keyword or data type for declaring long integers in JavaScript, but you can use string representation for very large numbers. For example:

let largeNumber = "938493849384394839483948";

However, be aware that since this is stored as a string, arithmetic operations on this variable will require it to be parsed into a numeric type first.
