Get and Set by Object Path
Get and Set by Object Path is a reusable JavaScript snippet. Safely access and modify deeply nested object properties using dot-separated path strings (like lodash get/set). The full implementation: function get(obj, path, defaultValue = undefined) { const keys = Array.isArray(path) ? path : path.split(/[.[\]]/).filter(Boolean) let result = obj for (const key of keys) { if (result === null || result === undefined) return defaultValue result = result[key] } return result !== undefined ? result : defaultValue } function set(obj, path, value) { const keys = Array.isArray(path) ? path : path.split(/[.[\]]/).filter(Boolean) let current = obj for (let i = 0; i < keys.length - 1; i++) { if (!(keys[i] in… This snippet uses only standard JavaScript with no dependencies, so it runs in modern browsers and Node.js alike.
