but on console it is showing

let myWork = [];

for(let i = 1; i <= 10; i++){

 let stat = i % 2 ? true : false;

 let temp ={
  name: `Lesson${i}`,
  status: stat   
 }

myWork.push(temp);

document.write(myWork[i].name+"<br>");
}

>Solution :

Its a simple issue, when you push to the array the position starts from 0, but your i starts from 1

See below.

let myWork = [];

for (let i = 0; i <= 10; i++) {

  let stat = i % 2 ? true : false;

  let temp = {
    name: `Lesson${i}`,
    status: stat
  }

  myWork.push(temp);

  document.write(myWork[i].name + "<br>");
}

If you want to start from Lesson1 try this

let myWork = [];

for (let i = 1; i <= 10; i++) {

  let stat = i % 2 ? true : false;

  let temp = {
    name: `Lesson${i}`,
    status: stat
  }

  myWork.push(temp);

  document.write(myWork[i - 1].name + "<br>");
}
