Set/Get element custom element properties

I'm trying to add a custom property to an existing element by I find it impossible.

There's a Map of attributes to my element but there's not properties Map.

I tried doing something like this:

el.someProperty = 'Some value';

but this line produced an error that el does not have get$someProperty.

I would like to do something similar to jQuery that you can just use 

el.prop('propName', 'value');

Thanks.

Use

el.attributes['someProperty'] = 'Some value';

if that doesn't work use

el.dataset['someProperty'] = 'Some value';

this way the added attribute will get a data prefix and probably named data-some-property (haven't tested)
