Different methods to get unique array in JavaScript Method-1: Use the Set object Within the JavaScript environment, there is a native and built-in object called Set, which allows us to store unique values of any data type. The collections of values within a Set object may only occur once,...
编写一个JavaScript函数,实现数组的去重。```javascriptfunction uniqueArray(arr) {return arr.filter((item, index, array) => {return array.indexOf(item) === index;});}```通过不断地练习和思考,我们可以更好地掌握JavaScript编程语言,提高自己的编程能力。希望以上的课后习题答案能够帮助大家更好地理解和...
To make an array uniqued, we can use Set() from Javascript. const ary = ["a", "b", "c", "a", "d", "c"]; console.log(newSet(ary)); We can see that all the duplicated value have been removed, now the only thing we need to do is convert Set to Array. So we have Arr...
var array=document.getElementById("neirong").value.split("\n"); for(var i in array){ temp=array[i]; hasValue=false; for(var j in rntArray){ if(temp===rntArray[j]){ hasValue=true; break; } } if(hasValue===false){ rntArray.push(temp); } } document.getElementById("neirong1"...
JavaScript Array: Exercise-45 with Solution Write a JavaScript program to find all the unique values in a set of numbers. Create a new Set() from the given array to discard duplicated values. Use the spread operator (...) to convert it back to an array ...
push_back(array1[i]); 17 18 vector<int>::iterator new_end; 19 new_end=unique(vector1.begin(),vector1.end()); //"删除"相邻的重复元素 20 assert(vector1.size()==N); 21 22 vector1.erase(new_end,vector1.end()); //删除(真正的删除)重复的元素 23 copy(vector1.begin(),vector1....
JavaScript中没有内置的unique函数,但可以通过自定义函数来实现类似的功能,通常使用Set数据结构来去除重复值。例如: function unique(array, mode = 'sorted') { if (!Array.isArray(array)) { throw new TypeError("Input must be an array"); } // 使用 Set 去重 let uniqueArray = [...new Set(array...
