— Ye, show me what they sell in *B* like some online-shop example.. that's not a trade but gambling
First = 2 in [1, 2];const second = '2' in [0, 1, 2];console.log(first, second);Output : false,true.Can someone,please explain.
— In array in checks for indexes and in object it checks for keys
— Coz,its checking for an index 2 in the first which isn't there so it returns false ? Second case ? Why it's returning true as output ?

— Second case there are 3 elements in the array hence index 2 exists
— But '2' is a string,right ?Aren't we checking for a string '2' in the array ? #Confused.
— Coerced ?
— Array index is integer
— U prolly mix up Array.prototype.includes and the object key in operator
— In just controls if the key existsIn your example you got the VALUES 1 and 2, but they got keys which are 0 and 1
— Thnx Mate!🤝
