如何从Node.js中的数组中删除特定的值

我有一个值的数组

var test =[]; test [1] = [ {"myself":true,chat_user:11,"message":"Hi"}, {"myself":true,chat_user:11,"message":"Evida"}, {"myself":false,chat_user:11,"message":"yes"}, ] test [6] = [ {"myself":true,chat_user:13,"message":"Hi"}, {"myself":true,chat_user:13,"message":"Evida"}, {"myself":false,chat_user:13,"message":"yes"}, ] test [9] = [ {"myself":true,chat_user:22,"message":"Hi"}, {"myself":true,chat_user:22,"message":"Evida"}, {"myself":false,chat_user:22,"message":"yes"}, ] 

现在我必须删除入口testing[6],需要得到剩余的数组

  test [1] = [ {"myself":true,chat_user:11,"message":"Hi"}, {"myself":true,chat_user:11,"message":"Evida"}, {"myself":false,chat_user:11,"message":"yes"}, ] test [9] = [ {"myself":true,chat_user:22,"message":"Hi"}, {"myself":true,chat_user:22,"message":"Evida"}, {"myself":false,chat_user:22,"message":"yes"}, ] 

有没有在节点js的function,为此?

提前致谢
