JSON.canonicalize = (value) => JSON.stringify(value, (_, value) => { if (value && typeof value === 'object' && !Array.isArray(value)) { const withSortedKeys = {} const keys = Object.getOwnPropertyNames(value) keys.sort() keys.forEach(key => withSortedKeys[key] = value[key]) value = withSortedKeys } return value })
