Implement a function conformsTo(obj, source) that checks if the given object satisfies the conditions defined in the source object.

The function should:

• Return true if for every key in source, the corresponding value in obj passes the predicate function in source.
• Return false otherwise.
• If a key in source does not exist in obj, treat it as failing the predicate.

Example

const obj = { a: 5, b: 10 };
const source = { a: x => x > 0, b: y => y < 20 };
conformsTo(obj, source); // true

const source2 = { a: x => x < 0 };
conformsTo(obj, source2); // false
