If you're launching a tech startup, there's a high possibility that your company won't have a budget for well-qualified frontend developers. The business want to hire cheap developers, but the tech side don't wont to fix their bugs

The solution to that problem is to use declarative programming. I wrote a declarative view engine which helps to reduce app costs by eliminating imperative code errors

{
    type: FieldType.Text,
    title: 'Only number allowed',
    description: 'Which will not be greater or lower than 42',
    name: 'text',
    isInvalid(obj) {
        if (isNaN(obj.text)) {
            return 'It is not a number';
        }
        return null;
    },
},
