 ## Selectors
 
-With specificity, comes great responsibility. Broad selectors allow us to be efficient, yet can have adverse consequences if not tested. Location-specific selectors can save us time, but will quickly lead to a cluttered stylesheet. Exercise your best judgement to create selectors that find the right balance between contributing to the overall style and layout of the DOM.

 - Similar to the [WordPress PHP Coding Standards](https://developer.wordpress.org/coding-standards/wordpress-coding-standards/php/#naming-conventions) for file names, use lowercase and separate words with hyphens when naming selectors. Avoid camelcase and underscores.
 - Use human readable selectors that describe what element(s) they style.

 An exception to camel case is made for constant values which are never intended to be reassigned or mutated. Such variables must use the [SCREAMING_SNAKE_CASE convention](https://en.wikipedia.org/wiki/Snake_case#History).
 
-In almost all cases, a constant should be defined in the top-most scope of a file. It is important to note that [JavaScript’s `const` assignment](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const) is conceptually more limited than what is implied here, where a value assigned by `const` in JavaScript can in-fact be mutated, and is only protected against reassignment. A constant as defined in these coding guidelines applies only to values which are expected to never change, and is a strategy for developers to communicate intent moreso than it is a technical restriction.

+Pre-increment/decrement should be favored over post-increment/decrement for stand-alone statements.
 
 Pre-increment/decrement will increment/decrement and then return, while post-increment/decrement will return and then increment/decrement.
 Using the "pre" version is slightly more performant and can prevent future bugs when code gets moved around.
