vara=[1,2,3,4,4]; varb=[]; varC={};//the IndexOf property returns 1 for a non-existent element, otherwise the specified position of the character is returned.//For (i in a) {//if (B.indexof (A[i]) ==-1) {//B.push (A[i])//// }// }//method Two creates an empty variable by judging whether the variable has an assigned Boolean value to the variable for(varI=0; i){ if(!C[a[i]]) {C[a[i]]=true; B.push (A[i]); }} console.log (b);An array of front-end interviews to

This method is not available if the order of the array is not changed to be heavy.The third method of thinking:1. Create a new array to hold t

use a self-executing anonymous function to do a traversal of the array, because Newarr is a global variable, after execution will not be destroyed, but return to go out, the final printing results are [1,2,3,4];This is es5 the most unadorned writing, can be said to be a "ancient writing" bar, ES6 has a structure called set, it is born with the cross-specific, that is sure there will not be repeated, see a piece of code to know.1 var s=New Set (arr); // the result is set{1,2,3,4} 2 v

indexof.To determine the efficiency of these three methods, I made a test program, generated an array of 10000-length random numbers, and then used several methods to test the execution time. The results show that the second method is much faster than the other two methods. However, the memory footprint should be the second method more, because a hash table. This is the so-called space change time. This is the test page, you can also go to see.The fourth method:Array.prototype.unique4 = functio

Below Chongqing seo on how to exchange links to talk about their own experience, for you to sum up the following points. First, check whether the site has the right to drop or be K This is the first step in exchanging links that you need to check. If t

New an array that holds the unique elements that have been traversed.function Uniquearr (list) {var newarr= [list[0]];for (Var i=1;ivar isrepeat = false;for (Var j=0;jif (list[i] = = Newarr[j]) {isrepeat= true;Break}}if (!isrepeat) {Newarr.push (List[i]);}}return NEWARR;}var arr=[' A ', ' B ', ' C ', ' A ', ' B '];Uniquearr (arr); Output:["A", "B", "C"]2, by first sorting, and then compared with the adjacent elements to the weight (after s

field is empty (null), it is not recommended to Jianjian the word index.Please remember that there must be a business need to build the index. For example, in a commodity table, we often have to query according to name, if there is no index, query speed is very slow, then we need to build an index. However, in project development, it is not necessary to index a number if it is not often queried according to the product number.Finally, the index is to pay a price, nothing to build, at the same t
