cast numbers to strings in a nested object (nodejs)

assuming a complex nested object such as:

{ a: [{b: 12}, {c: {r: [1, 2, {g: 55} ] } }, 5], f: {h: 76}}

I’d like to cast all numbers to strings in nodejs. external libraries (e.g. lodash) are encouraged.

{ a: [{b: '12'}, {c: {r: ['1', '2', {g: '55'} ] } }, '5'], f: {h: '76'}}

Thank you!
