mergeArrays(array1, array2);
Theconcat()method is used to join two or more arrays. This method does not change the existing arrays, but returns a new array, containing the values of the joined arrays. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 console.log(a.concat(b)); 当字符串处理 代码语言:javascript 代码运...
只使用命令式技术,我们可以这样写: functionmerge2dArrayIntoOne(arrays) {varcount = arrays.length;varmerged =newArray(count);varc =0;for(vari =0; i < count; ++i) {for(varj =0, jlen = arrays[i].length; j < jlen; ++j) { merged[c++] = arrays[i][j]; } }returnmerged } 并且使用...
30. Merge Arrays Without Duplicates Write a JavaScript function that merges two arrays and removes all duplicate elements. Test data : var array1 = [1, 2, 3]; var array2 = [2, 30, 1]; console.log(merge_array(array1, array2)); [3, 2, 30, 1] Click me to see the solution 31...
在上述示例中,mergeArraysByCondition()函数根据条件shouldMerge决定是否合并数组array1和array2。 JavaScript按条件拆分和合并数组是在实际开发中经常遇到的问题,例如根据某个属性值对数据进行分类或者将多个结果集合并在一起。它适用于各种前端开发场景,如数据处理、动态列表生成等。
