How to assign a variable for each item of the loop

for (var i = 0; i < dataForecast.list.length; i += 8) {
  const data = dataForecast.list[i].dt_txt;
}

This loops gives out 5 intended looped pieces of data but I'm struggling to assign each loop to its own variable.

It seems you want to dynamically generate and assign variable value. For this you can use eval() method like below:

dataArray = [1, 2, 3, 4, 5]
var x = 'data'

for (var i = 0; i < dataArray.length; i++) {
  eval('var ' + x + i + '= ' + dataArray[i] + ';');
}
console.log("data0=" + data0);
console.log("data1=" + data1);
console.log("data2=" + data2);
console.log("data3=" + data3);
console.log("data4=" + data4);

Note: It's not recommended to use eval() method due to security reasons. You can read more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval

Use an array

const dataArr = [];
for (var i = 0; i < dataForecast.list.length; i += 8) {
  const data = dataForecast.list[i].dt_txt;
  dataArr.push(data);
}
console.log(dataArr); // access the array
