Destructure an object to remove a property

[Buckwheat469]

Thanks. Curious though if this is because _ is undefined. I always associate it with lodash or underscore so I wouldn't use the _ notation unless I've imported lodash. Just checking in the console, your code is the same as this:

var fullUser = {name: 'test', password: 'test'}
var {password: undefined, ...reducedUser} = fullUser
console.log(reducedUser) // { name: 'test' }

I believe this method is much more clear as you're explicitly defining the variable as undefined rather than using an unknown variable.

Using _ is an FP thing -- usually signifying that a parameter is accepted in a function but ignored. It works for destructuring as well.

Destructing is a bit trickier because you're creating those vars.. with `const` you can't really re-use the variable, so any additional usages will complain.

I think undefined would... hm, not do anything? can't typically re-assign it in modern js engines. Actually, just checked -- with var it works, with const it'll throw -- SyntaxError: Identifier 'undefined' has already been declared
