Jquery is a swear word in professional front end contexts, the replacement is transpilation and dropping ie support.
Personally I used jquery up until react and babel got hot, now I never touch the dom directly with jquery and no longer have a need for the polyfill features as I rely on babel preset-env to support the browsers we have selected (especially for things like promises/async await/es6+ features)

A slang term that means “stop striving”, I’d say it’s loosely akin to the phrase “quiet quitting” but a bit more general.
