Script Preparation code:

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

Tests:

Chain
_.chain(data).filter(f => f.a === 'a').filter(f => f.b === 1).filter(f => f.b + 1 === 2).map(f => f.a).filter(f => f === 'a').value()
Native (with &&)
data.filter(f => f.a === 'a' && f.b === 1 && f.b + 1 === 2).map(f => f.a).filter(f => f === 'a')
Native (without &&)
data.filter(f => f.a === 'a').filter(f => f.b === 1).filter(f => f.b + 1 === 2).map(f => f.a).filter(f => f === 'a')
Flow
_.flow( _.filter(f => f.a === 'a'), _.filter(f => f.b === 1), _.filter(f => f.b + 1 === 2), _.map(f => f.a), _.filter(f => f === 'a') )(data)
