Lodash uniqBy多个数组？

我有数组：Lodash uniqBy多个数组？

[ [ '245', '0', '0.0100', '245,0,0.01' ], 
    [ '245', '1', '0.0100', '245,1,0.01' ], 
    [ '208', '0', '0.0300', '208,0,0.03' ], 
    [ '208', '0', '0.0500', '208,0,0.05' ], 
    [ '208', '0', '0.0600', '208,0,0.06' ] ]

，我需要通过[0]和[1]细胞这样获得独特的数组：

[ [ '245', '0', '0.0100', '245,0,0.01' ], 
    [ '245', '1', '0.0100', '245,1,0.01' ], 
    [ '208', '0', '0.0600', '208,0,0.06' ] ]

请帮助/

使用lodhash uniqBy()方法

var data = [ 
 
    ['245', '0', '0.0100', '245,0,0.01'], 
 
    ['245', '1', '0.0100', '245,1,0.01'], 
 
    ['208', '0', '0.0300', '208,0,0.03'], 
 
    ['208', '0', '0.0500', '208,0,0.05'], 
 
    ['208', '0', '0.0600', '208,0,0.06'] 
 
]; 
 

 
console.log(
 
    _.uniqBy(data, function(v) { 
 
    return v[0] + ' ' + v[1]; 
 
    }) 
 
)

非常感谢你！ – axon

@axon：很高兴帮助:) –

我得到['208'，'0'，'0.0300'，'208,0,0.03']也许它可能指定相反的独特元素？获得['208'，'0'，'0.0600'，'208,0,0.06'] – axon
