For example i have a array like that
var myArray = [
[1,2,3],
[4,5,6],
[7,8,9,10],
[[11,12],[13,14,15]]];
for (var i = 0;i < myArray.length;i++){
for(var j = 0 ;j< myArray[i].length;j++){
for(var k = 0;k< myArray[i][j].length;k++){
console.log(myArray[i],[j][k]);
}
}
}
But output is only 11,12,13,14,15. And i wanna print all the values Could some one help to fix Thank you in advance
Use e.g. Array.prototype.flat(), .flat(2) flattens to the level of 2 arrays deep.
var myArray = [
[1,2,3],
[4,5,6],
[7,8,9,10],
[[11,12],[13,14,15]]];
console.log(myArray.flat(2));
2?
You can use recursive function first pass it the whole array then loop it and check if the element you are accessing is array or digit if its array call the same function again and only pass it this element otherwise if its digit just print it
This works even when you dont know how many nested arrays you have otherwise use MWO answer
var myArray = [
[1,2,3],
[4,5,6],
[7,8,9,10],
[[11,12],[13,14,15]]];
function printArray(arr){
for(var i = 0; i < arr.length; i++){
if(Array.isArray(arr[i])){
printArray(arr[i]);
}else{
console.log(arr[i]);
}
}
}
printArray(myArray);This fucntion works for any depth of multi dimensional array. Using Recursion
var myArray = [1,2,33,44, [1,2,3], [[11,12],[13,14,15]]];
var myArray1 = [1,2,33,44, [[11,12],[13,14,15]]];
var deepFlattenArray = function (array){
var result = [];
array.forEach(function (element) {
if (Array.isArray(element)) {
result = result.concat(deepFlattenArray(element));
} else {
result.push(element);
}
});
return result;
};
console.log(deepFlattenArray(myArray));
// output = [ 1, 2, 33, 44, 1, 2, 3, 11, 12, 13, 14, 15]
console.log(deepFlattenArray(myArray1));
// output = [1, 2, 33, 44, 11, 12, 13, 14, 15 ]
x) that takes an array and iterates over the elements of that array. In the function test every element and if its an array callxwith that array....[1,2,3]is in the "second level" whereas[11,12]and[13,14,15]are in the "third level". So for instancemyArray[i][j].lengthwill beundefinedfori == 0
