* Checks if a given value is a number.

* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `number`.

|
* @param value The value to check if it is a number.
|
|
* @returns Returns `true` if `value` is a number, else `false`.
|
|

|
|
* @example
|
|
* const value1 = 123;
|
|
* const value2 = 'abc';
|
|
* const value3 = true;
|
|
*
|
|
* console.log(isNumber(value1)); // true
|
|
* console.log(isNumber(value2)); // false
|
|
* console.log(isNumber(value3)); // false
