从二维数组在Javascript中删除重复 [英] Removing duplicates from 2d array in Javascript

问题描述

什么将是一个很好的算法，以消除类似下面的阵列上易受骗的人......

What would be a nice algorithm to remove dupes on an array like below...

    var allwords = [

    ['3-hidroxitiramina', '3-hidroxitiramina'],

    ['3-hidroxitiramina', '3-hidroxitiramina'],

    ['3-in-1 block', 'bloqueo 3 en 1'],

    ['abacterial', 'abacteriano'],

    ['abacteriano', 'abacteriano'],

    ['abciximab', 'abciximab'],

...

只是为了澄清，我想的一个

Just to clarify, I would want one of the

['3-hidroxitiramina', '3-hidroxitiramina'],

要被删除，因此只有一个

To be removed, so there is just one

推荐答案

：误读，读你的澄清后，我会建议：

[edit]: misread, after reading your clarification I'd suggest:

 var i = allwords.length-1, prev='';
 do {
     if (allwords[i].join('/') === prev) {
    	allwords.splice(i,1);
     }
     prev = allwords[i].join('/');
 } while (i-- && i>-1);

（扭转循环是一个优化步骤）

(reversing the loop is a optimization step)
