JavaScript Mixin Pattern samjho (Hindi) — kisi bhi class ko superpowers do

JavaScript class ko sirf ek parent milta hai — toh logging, dirty-tracking, ya serialization jaise behaviors alag-alag unrelated classes mein kaise share karein? Mixins. Ek mixin bas methods ka bundle hai jise tum Object.assign se class ke prototype pe chadha dete ho — ek line, koi inheritance nahi. Is video mein: single-inheritance ki problem, fix (trait object + Object.assign), real code (dirtyTrackable trait), proof (ek bundle, teen unrelated classes), traps jinki wajah se mixins deprecate hue, aur modern replacements (subclass-factory mixins jahan super kaam karta hai, plus hooks/composables/decorators). React ne mixins 2016 mein hata diye — par tumhara browser inhi pe bana hai (Window, WindowOrWorkerGlobalScope ko mix-in karta hai — fetch aur setTimeout wahin se aate hain).
