I'm trying to factorize a method, will be passing in certain keywords into it, example keywordA, keywordB, and I want to perform certain actions with these keywords using jquery and Tether javascript library.

let wrapperTetherName = `${containerName}WrapperTether`;

This is ok and returns the right name example keywordAWrapperTether, keywordBWrapperTether

How do I do something like (obviously incorrect syntax) :

if (!this.`${wrapperTetherName}`) // this.wrapperTetherName returns undefined

Or any ideas for alternatives? I just want to check the existence of this.keywordAWrapperTetherName, if it doesn't exist then create a new instance of Tether for it, otherwise, destroy it.

Thanks! @Ry- , worked well, didnt think of it at first but it makes sense given `this` is an object – MIN S Dec 18 '19 at 20:59
