const parts = path.split('.');
let current = o;
for (let i = 0; i < parts.length - 1; i++) {
  current[parts[i]] = current[parts[i]] || {};
  current = current[parts[i]];
}
current[parts[parts.length - 1]] = value;
return o;

More JavaScript Snippets

Count Object Properties

Count the number of enumerable properties in an object.

Deep Clone Object

Create a deep copy of an object (handles nested objects and arrays).

Deep Equal

Check if two values are deeply equal by recursively comparing all nested properties. Works with objects, arrays, and primitives.

Deep Freeze Object

Recursively freeze an object and all nested objects to make them immutable.

Deep Merge Objects

Deep merge two objects, combining nested properties.

Flatten Object

Flatten a nested object to a single level with dot notation keys.
