If I want to find the MDN page for destructuring assignment in JavaScript I know I don’t need to add JavaScript or MDN, I can just search for “Array Destructuring”, and the top half dozen results are all JavaScript.
And if I want to search for say which of call/apply takes an array, or even confirm what version of php a new flag is introduced, I’m not searching for “$language programming $feature”.
I’m using DDG bangs to reduce the noise from the start and take me straight to a site specific result : `!mdn function apply` or eg `!php preg_split`.
