var data = Array(10000000).fill({ a: 'a', b: 1 });

Tests:

_.chain(data).filter(f => f.a === 'a').filter(f => f.b === 1).map(f => f.a).value()

 
_.chain(data).filter(f => f.a === 'a').filter(f => f.b === 1).map(f => f.a).value()

Without chain
data.filter(f => f.a === 'a' && f.b === 1).map(f => f.a)
data.filter(f => f.a === 'a' && f.b === 1).map(f => f.a)
