/**
|
|
* Checks if the given value is boolean.
|
|
*
|
|
* This function tests whether the provided value is strictly `boolean`.
|
|
* It returns `true` if the value is `boolean`, and `false` otherwise.
|
|
*
|
|
* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `boolean`.
|
|
*
|
|
* @param value - The Value to test if it is boolean.
|
|
* @returns True if the value is boolean, false otherwise.
|
|
*
|
|
* @example
|
|
*
|
|
* const value1 = true;
|
|
* const value2 = 0;
|
|
* const value3 = 'abc';
|
|
*
|
|
* console.log(isBoolean(value1)); // true
|
|
* console.log(isBoolean(value2)); // false
|
|
* console.log(isBoolean(value3)); // false
|
|
