Script Preparation code:

var params = [[1, 2], ["hello", true, 7], [null, undefined, {}], [1, 2, 3, 4, 5], [false, true, {}, {}, {}]];

Tests:

Array.flat
params.flat();
reduce + concat
params.reduce((acc, val) => acc.concat(val), []);
reduce + destructure
params.reduce((acc, curr) => [...acc, ...curr], []);
reduce + push
params.reduce((acc, curr) => (acc.push(...curr), acc), []);
lodash.flatten
_.flatten(params)
destructuring
[ ...params[0], ...params[1], ...params[2], ...params[3], ...params[4] ]
