I want to access inner array data from array object of data in TypeScript

Question

myData = [{
    "Total_Demand": "800",
    "weekly": [
      {
        "CycleTime": .65,
        "Demand": 650,
      },
      {
        "CycleTime": .75,
        "Demand": 820,
      }

    ]
}]

if i do console.log("The Data of weekly is", this.myData[0].weekly[0]);

I'm able to get the data object but not able to iterate

for(let i=0; i > this.myData[0].weekly.length; i++) {
   this.WeeklyData = [this.myData[0].weekly[i]].push(this.WeeklyData);
 }

WeeklyData is not having data it is showing as undefined

Can you try this

this.WeeklyData = [...this.myData[0].weekly[i], ...this.WeeklyData];

this.WeeklyData is declared as any type and assigned empty array. this.WeeklyData = [];

You have it reversed... it should be

this.WeeklyData = [];
for(let i=0; i <= this.myData[0].weekly.length; i++) {
   this.WeeklyData.push(this.myData[0].weekly[i]);
}

And, of course you have i > where it should be i <=

You can also push the whole array, as in

this.WeeklyData.push(this.myData[0].weekly);

for(let i=0; i < this.myData[0].weekly.length; i++) {
  this.WeeklyData = [...this.WeeklyData,this.myData[0].weekly[i]]
