Convert string to variable name in JavaScript

Question

I’ve looked for solutions, but couldn’t find any that work.

I have a variable called onlyVideo.

\"onlyVideo\" the string gets passe

Answer 1

let me make it more clear

function changeStringToVariable(variable, value){
window[variable]=value
}
changeStringToVariable("name", "john doe");
console.log(name);
//this outputs: john doe
let file="newFile";
changeStringToVariable(file, "text file");
console.log(newFile);
//this outputs: text file
