Simple example of array separation of native js

JS operations on arrays will also be encountered in ordinary projects. In addition to some operations that increase or decrease, there is another more important operation that is the deduplication of arrays. Through the deduplication of arrays, we can clean up multiple duplicate arrays in an array, leaving only non-duplications. In addition, I will introduce a native array deduplication method.

= function(){ 
  for(var i=0;i<;i++){ 
    for(var j=i+1;j<;j++){ 
      if(this[i]==this[j]){ 
        (i,1); 
        i=i-1; 
      } 
    } 
  } 
} 
 
var temp=[1,2,3,3,4,5,5]; 
(); 
alert(temp) 

By using the prototype of the array, we define the method check(), in which we compare the two arrays, transfer the same splice(), and then define the array and assign the method to operate the array to obtain the result we need.

The above article is a simple example of the native js array except for duplication. This is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
