Tests:

forEach concat
var a = [{nested: [ "hello", true, 7 ]}, {nested: [ 1, 2 ]}]; let b = []; a.forEach((item) => { b = b.concat(item.nested); });
Reduce push
var a = [{nested: [ "hello", true, 7 ]}, {nested: [ 1, 2 ]}]; const b = a.reduce((acc, item) => { acc.push(...item.nested); return acc }, []);
Reduce concat
var a = [{nested: [ "hello", true, 7 ]}, {nested: [ 1, 2 ]}]; const b = a.reduce((acc, item) => { return acc.concat(item.nested); }, []);
forEach push
var a = [{nested: [ "hello", true, 7 ]}, {nested: [ 1, 2 ]}]; let b = []; a.forEach((item) => { b.push(...item.nested); });
