Lodash _.unset

Overview

The lodash _.unset method is a powerful utility function that is used to remove a property from an object. The method takes two parameters, the first being the object to modify and the second being the path of the property to remove.

The path parameter can be defined as either a string or an array of strings. If an array is used, each element represents a level in the property hierarchy of the object. For example, if the object has a property called a that is an object with a property called b, the path would be defined as ['a', 'b'].

The _.unset method can also be used to remove elements from arrays by using a numeric path. For example, if the object has an array called a, the path to remove the first element would be defined as ['a', 0].

One of the key features of the _.unset method is that it automatically creates nested properties if they do not exist. For example, if the object has a property called a but not b, calling _.unset(obj, 'a.b') will create the b property.

The _.unset method returns a boolean value indicating whether the property was successfully removed. If the property did not exist, the method returns true.

Overall, the _.unset method is a simple but powerful utility that can be used to remove properties and elements from objects and arrays in a flexible way.
