JavaScript(JS) number method - max_safe_integer

The Number.MAX_SAFE_INTEGER property in JavaScript represents the maximum safe integer that can be exactly represented as a double-precision floating-point number. It has a value of 9007199254740991 or 2^53 - 1.

Here's an example usage:

console.log(Number.MAX_SAFE_INTEGER); // 9007199254740991
console.log(Number.MAX_SAFE_INTEGER + 1); // 9007199254740992
console.log(Number.MAX_SAFE_INTEGER + 2); // 9007199254740992

In the above example, the Number.MAX_SAFE_INTEGER property is used to get the maximum safe integer that can be represented in JavaScript. The second call returns 9007199254740992, which is the next integer after Number.MAX_SAFE_INTEGER, but it is not a safe integer. The third call also returns 9007199254740992 because adding 2 to Number.MAX_SAFE_INTEGER does not change the result due to the precision limitation of the double-precision floating-point format.
