How can I print a nested array in console using javascript by using for of loop?

Question

I want to print a array of string which contains the cities names line by line.

Answer 1

let array = [[11,12,13,14],[21,22,23,24,25],[31,32,33]];

for(let i=0;i<array.length;i++)
for(let j=0;j<array[i].length;j++)
console.log(array[i][j])

Answer 2

Prashant Singh check it .

let array = [90,91,true,false,[11,12,13,14],[21,22,23,24,25],[31,32,33],["i","am","the","one"],"md","sayed","al","sahab"]
for(let i of array){
if (typeof(i)!="object"){
console.log(i)
}
else{
for(let j of i){
console.log(j)
}
}
}

Answer 3

Using recursion and checking if element is array or not.

a=[1, 2,3,[4, 5]]

function print(arr){

for(let i of arr){
if(Array.isArray(i)){
print(i);
}
else{
console.log(i);
}
}
}

print(a);

Answer 4

You need a nested loop.

For a 2-dimensional array, you could do:

const nested_list = [ ["a", "b"], ["c", "d" ]]

for (let item of nested_list) {
item.forEach(innerItem =>
console.log(innerItem))
}

You can do another for of loop instead of forEach as the inner loop if you wanted.

Answer 5

let array = [[11,12,13,14],[21,22,23,24,25],[31,32,33]];

for(let i of array)
for(let j of i)
console.log(j)

Answer 6

let array = [[11,12,13,14],[21,22,23,24,25],[31,32,33]];

for(let i of array)
for(let j of i)
console.log(j)
It is right in case of numbers but If I want to print a array of string,it comes one alphabet at a time.
