The use of "with" function

Question

I have a js code to deserialize a JS fn from a serialized Function the reason is that I want to transfer it to my web worker it's compatible with web and node so that's good but I found out that it's not recommended to use what do it do
is there any alternative?

function deserializeFn(serializedObj) {
let fn = new Function('with(this) { return ' + serializedObj.value + '; }');
return fn.call(serializedObj.scope);
}

A better approach would be not to use "with"

```
const serializedObj = { value: 'return x + y;' };

function deserializeFn(serializedObj) {
const { value } = serializedObj;
const fn = new Function('x', 'y', value);
return fn;
}

const deserializedFn = deserializeFn(serializedObj);
const result = deserializedFn(5, 3); // result will be 8
document.write(result);
```
