Defining a variable using template strings [duplicate]

Question

Is it possible to create a variable using template strings? Here is a simple example of what I want to achieve:

    let times, hours="fullTime";

    if (hours === "fullTime") {
        times = ["Day", "Night"];
      } else {
        times = ["Day"];
      }

      times.forEach((time) => {
        const `${time}shift` = "8 hours";
      }

      console.log(DayShift);

log: "8 hours"

I want a new variable with a different name to be defined everytime that forEach loop iterates.

Thanks

For global variable, you can use window[time+"shift"] = "8 hours";. But you'd probably be better off setting that within a better-scoped JSON object property rather than on the window object. — Marc

Of course, just store them in an object. Simply add keys to the object.

let times, hours = "fullTime";

if (hours === "fullTime") {
  times = ["Day", "Night"];
} else {
  times = ["Day"];
}

let variables = {};

times.forEach((time) => {
  variables[`${time}shift`] = "8 hours";
});

console.log(variables);
console.log(variables.Dayshift);
