    You can undefine the variable:

    var var1 = 'hello world';
var1 = undefined;
console.log(var1);

    var var1 = ‘hello world’;
    delete var1;

    You can achieve this by using ‘delete’. please be cautious when using the delete operator in real cod.

    If this is NOT your answer please do let me know.
