/**
|
||
* 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 also serves as a type predicate in TypeScript,
|
||
* narrowing the type of the argument to `number`.
|
||
*
|
||
* @param value - The value to check
|
||
* @returns `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
