extraneous "!" in the text?
The "!" is shown in the section below:
`When Boolean is called with argument value, the following steps are taken:
Let b be ! ToBoolean(value).
If NewTarget is undefined, return b.
Let O be ? OrdinaryCreateFromConstructor(NewTarget, "%BooleanPrototype%", « [[BooleanData]] »).
Set O.[[BooleanData]] to b.
Return O.`
However, the following section seems to indicate that there is not a "!" in the section above and the ECMA-262(2019 edition) don't have a "!" in there either. I think the "!" should be removed.
Step 1 casts value (the function argument) to a Boolean value. Interestingly there isn’t a ? or ! shorthand for this step, but usually not having a Completion Record shorthand means the same thing as !. So step 1 cannot throw an exception.
Indeed. There has been recently a few clean-ups on the usage of these shorthands in the spec. See https://github.com/tc39/ecma262/pull/1622 and https://github.com/tc39/ecma262/pulls?q=label%3A%22completion+records%22.
I'm a beginner contributor and I was looking for easy issues to fix when I found this one. I can take care of the ! removal (In spite I don't know what are you talking about there)
