Turn Javascript string to function

Question

I got a string that I want to turn into a function. I've tried eval and that works just fine, but I've heard eval is dangerous.

function setProductList(list) {
    for(typeList of list) {
        let modelName = `model${typeList[0].type}Products`
        typeList = JSON.stringify(typeList)
        
        let model = Function("return " + modelName)()
        model.setData(typeList)
    }
}

So, I want to turn modelName into a function. If I do modelName = Eval(modelName) it works perfectly and I can use modelName.setData().

But with this method I am trying right now, it says modelXXProducts is not defined. How can I turn the string into a function without eval?
