How Can I Dynamically Set JavaScript Variables Using Strings as Names?

Setting Variables Dynamically Using String to Variable Name Conversion in JavaScript

While searching for solutions to dynamically set variables using strings as variable names, many users encounter challenges. For instance, if you have a variable named onlyVideo and you want to set the value of onlyVideo within a function, the following question arises:

"How can I dynamically assign a new value to the variable onlyVideo inside a function based on a passed string, rather than using hard-coded if statements?"

The text suggests that a better approach might exist, such as using JavaScript objects, but for beginners, a simpler method is explained. This method involves using the window object to set global variables:

window["onlyVideo"] = "new_value"; // Sets the global variable `onlyVideo`
Copy after login

In this specific case, window["onlyVideo"] allows you to set the onlyVideo variable's value dynamically within a function.
