Script Preparation code:

var fp = _.noConflict();

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
fp.flow( fp.filter(f => f.a === 'a'), fp.filter(f => f.b === 1), fp.filter(f => f.b + 1 === 2), fp.map(f => f.a), fp.filter(f => f === 'a') )(data)
