* Checks whether a value is a JavaScript primitive.
|
|
* JavaScript primitives include null, undefined, strings, numbers, booleans, symbols, and bigints.
|
|
*
|
|
* @param value The value to check.
|
|
* @returns Returns true if `value` is a primitive, false otherwise.
|
|
*
|
|
* @example
|
|
* isPrimitive(null); // true
|
|
* isPrimitive(undefined); // true
|
|
* isPrimitive('123'); // true
|
|
* isPrimitive(false); // true
|
|
* isPrimitive(true); // true
|
|
* isPrimitive(Symbol('a')); // true
|
|
* isPrimitive(123n); // true
|
|
* isPrimitive({}); // false
|
|
* isPrimitive(new Date()); // false
|
|
* isPrimitive(new Map()); // false
|
|
* isPrimitive(new Set()); // false
|
|
* isPrimitive([1, 2, 3]); // false
