Delete multiple object properties?

Question

I create an object with multiple properties -

var objOpts = {   option1: 'Option1',   option2: 'Option2',   option2: 'Option3' }; 

I then add some more properties later on -

objOpts.option4 = 'Option4' objOpts.option5 = 'Option5' 

I'm then done with the two latter created properties ('Option4' & 'Option5') and I want to clear/delete both.

Currently I'd do it like so -

delete objOpts.option4 delete objOpts.option5 

Is there another way to go about doing this? Imagine I'd added 5 more properties and needed to clear/delete them all that'd be five lines of almost identical 'delete' code

ES6 provides an elegant solution to this: Rest in Object Destructuring:

let { a, b, ...rest } = { a: 10, b: 20, c: 30, d: 40 }; console.log(rest); // { c: 30, d: 40 } 

Note that this doesn't mutate the original object, but some folks might still find this useful.
