/**
 * creates a new object (newObj) by copying all the properties from the original
 * object using the spread operator ({ ...obj }). Then, it iterates over each
 * key in keysToOmit using forEach, and deletes those keys from the newObj
 * using the delete keyword.
 * @param obj the original object
 * @param keysToOmit the keys to omit
 * @returns a new object (newObj) that includes all properties of the original object
 * except the ones specified in keysToOmit.
 *
 *
 * @example
 * For example, let's say you have an object like this:
 *
 * ```javascript
 * const originalObject = {
 *   name: 'John',
 *   age: 25,
 *   city: 'New York',
 *   country: 'USA'
 * };
 * ```
 *
 * To omit the `name` and `age` keys, you can use the `omit` function like this:
 *
 * ```javascript
 * const newObj = omit(originalObject, ['name', 'age']);
 *
 * console.log(newObj);
 * ```
 *
 * The output will be:
 *
 * ```javascript
 * { city: 'New York', country: 'USA' }
 * ```
