Logical assignment operators in JavaScript: small syntax, big wins
Interesting, but not being able to use it with logical assignment seems to make it less practical. Update: Just discovered this feature was implemented back in 2020, but I had never known about it before, which is strange. More on reddit.com

Understanding the Spread Operator in JavaScript
Spread Operators for Arrays The core piece to know is the ... syntax. This is the spread operator, and it essentially takes either an array or an object and expands it into its set of items. Careful here. Spreading into an array only works on objects if that object is iterable. [...{}] // Error, not iterable [...{ *[Symbol.iterator](){} }] // ok Array objects are inherently iterable so are ok, that is unless you break them :P const arr = [] arr[Symbol.iterator] = null [...arr] // Error, not iterable This does not apply to spreading in objects since that maps to Object.assign() which only cares about own enumerable properties. {...{}} // ok (doesn't have to be iterable) More on reddit.com

Basic math in JavaScript — numbers and operators - Learn web development | MDN
August 18, 2025 - This is because of operator precedence — some operators are applied before others when calculating the result of a calculation (referred to as an expression, in programming). Operator precedence in JavaScript is the same as is taught in math classes in school — multiply and divide are always done first, then add and subtract (the calculation is always evaluated from left to right).

All the comparison operators above can also be used on strings: let text1 = "A"; let text2 = "B"; let result = text1 < text2; Try it Yourself » ... Comparing data of different types may give unexpected results. When comparing a string with a number, JavaScript will convert the string to a number when doing the comparison.
