The example was wrong. It stated that ?= is similar to JS || when the || will affect not only not defined scenario but also any falsy values (values that evaluate as false)

There are way to many differences between the 2:

1. window.var = false;
2. window.var = 0;
3. window.var = '';
4. window.var = [];
5. window.var = null;

window.var ?= 'something'
console.log(window.var) ->
1. false
2. 0
3. ''
4. []
5. 'something'

window.var ||= 'something'
console.log(window.var) ->
1. 'something'
2. 'something'
3. 'something'
4. []
5. 'something'
