- The logical OR assignment... ||= an ES 12 update in ECMAScript 2021 that looks bizarre but is another handy way to check for values before doing "x" operation. It checks to see if the thing on the left has no value (is falsy) and if so, overwrites it with the right! It's a useful way to assign a variable as long as the variable no "no value."

Thanks Rob!
