}), ...Array(1000000).fill({
    filtering: true,
    mapping: 42
})];

Tests:

.find
let next = data.find((e, index) => e.filtering === true); let next_index = data.indexOf(next); // console.log('next_login - ', next_login); // console.log('next_login_index - ', next_login_index); console.log('Index: ', next_index)
while loop
let loopStop = false; let i = 0; while (i < data.length && !loopStop) { i++; if (data[i] && data[i].filtering === true) { i--; loopStop = true; } } console.log('Index: ', i)
