Gets the target value in a nested JSON object, based on the given key.

  • Use the in operator to check if target exists in obj.
  • If found, return the value of obj[target].
  • Otherwise use Object.values(obj) and Array.prototype.reduce() to recursively call dig on each nested object until the first matching key/value pair is found.
const dig = (obj, target) => target in obj ? obj[target] : Object.values(obj).reduce((acc, val) => { if (acc !== undefined) return acc; if (typeof val === 'object') return dig(val, target); }, undefined);
const data = { level1: { level2: { level3: 'some data' } } }; dig(data, 'level3'); // 'some data' dig(data, 'level4'); // undefined
