For most things, yes. But this is JavaScript, the language where intransitive equality, implicit object-to-primitive casting and mutable global objects must be used in all slight-above-trivial code. Where `typeof` is useless and wrong, but nonetheless necessary; where there are seven different ways to parse a number, with six different semantics… there's a reason that “JavaScript: The Good Parts” is such a short book. https://blog.klipse.tech/assets/js_good_parts.jpg https://blog.klipse.tech/assets/js_good_parts.jpg Somebody who knows the good parts of JavaScript is a JavaScript expert. You want somebody who can write good JavaScript, and using the bad parts well has nothing on using the good parts adequately.
