Getting Deep Object Values with Nested Path Strings

In JavaScript, accessing nested object values can become cumbersome when the structure is deeply hierarchical. To simplify this task, consider utilizing a function that allows you to obtain values by specifying a path as a string.

Solution:

The provided JavaScript function, deep_value, enables you to traverse nested objects and retrieve values based on string paths. For instance, given an object like:

var obj = {
  foo: { bar: 'baz' }
};

You can access obj.foo.bar by passing the string "foo.bar" to the function:

function deep_value(obj, path){
    var segments = path.split('.');
    for (var i = 0; i < segments.length; i++){
        obj = obj[segments[i]];
    };
    return obj;
};

The function iterates through the segments of the path string and drills down into the nested object structure. It returns the desired value, providing a convenient and efficient way to access deep object attributes.
