nested arrays code example

Example 1: Accessing Nested Arrays

var myPlants = [
  {
    type: "flowers",
    list: [
      "rose",
      "tulip",
      "dandelion"
    ]
  },
  {
    type: "trees",
    list: [
      "fir",
      "pine",
      "birch"
    ]
  }
];

var secondTree = myPlants[1].list[1]; 

console.log(myPlants[1].list[1]);

Example 2: nested array loop in javascript

let chunked = [[1,2,3], [4,5,6], [7,8,9]];

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

Example 3: javascript nested array

//2-dimensional(nested) array
var array = [[0,2,3,7,2,2,1],[1,2,6,3,7,0,3]]
