Tests:

Some
const hasResultArrays = Object.values(data).some(e => e.username === 'titi')
key iterator
let hasResultArrays = false; for (const key in data) { if (Array.isArray(data[key])) { hasResultArrays = true; break; } }
values iterator
let hasResultArrays = false; for (const value of Object.values(data)) { if (Array.isArray(value)) { hasResultArrays = true; break; } }
find
const hasResultArrays = Object.values(data).find(e => e.username === 'titi')
classical
let hasResultArrays = false; const keys = Object.keys(data) for (let i = 0, il = keys.length; i < il; ++i) { if (Array.isArray(data[keys[i]])) { hasResultArrays = true; break; } }
