** Operator in an es6 Escmascript feature a short hand method used for raising numbers to their power

With statement in JavaScript

-
JavaScript 'with statement' is a simplified way to access object properties as variables. Take for instance; const dog = "puppy" const mascots = {     'tux': "tuxedo",     'cow': 'cow' } with(mascots) {     console.log(tux)     // tuxedo     console.log(cow)     // cow     console.log(dog)     // puppy } properties of mascots are converted to variables accessible within the with block 'dog' is not part of mascots and as a fallback, dog global is returned. At the time of writing this post with statement is discouraged. It's not allowed in 'safe mode' With the above sample you can do the same thing using destructureing operator const {cow, dog, tux} = mascots console.log(tux) // tuxedo console.log(cow) // cow console.log(dog) // puppy
