Function isSafeInteger

Alias

isSafeInteger(value?): value is number
Checks if value is a safe integer (between -(2^53 – 1) and (2^53 – 1), inclusive).

A safe integer is an integer that can be precisely represented as a number in JavaScript, without any other integer being rounded to it.

This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to number.
Parameters
- Optionalvalue: unknown
  The value to check
Returns value is number
true if value is an integer and between the safe values, otherwise false
Example
```
isSafeInteger(3); // Returns: true
isSafeInteger(Number.MIN_SAFE_INTEGER - 1); // Returns: false
isSafeInteger(1n); // Returns: false
isSafeInteger('1'); // Returns: false
```
