The core concept behind useCallback is to maintain referential equality of the memoized function across renders. This means that if the dependencies specified in the second argument of useCallback remain unchanged, React will return the same instance of the memoized function. This will avoid unnec...
What is a Callback function? When we call a function that function will call other function by itself is called callback function. example: function add(a,b,callback){ return callback(a,b) } add(1, 2, function(a,b){ return a+b; }) Output: 3 Did you notice, in the above code...
} with React Compiler, we don't need to do that anymore, So what exactly does the compiler do in this cases? It doesn't use useMemo or useCallback at all, Instead, the compiler manualy caches the values and resuses them if dependencies stay the same. 🚨Do we need to manually memo...

However, useCallback() is only used for memoizing functions rather than values. When we used the React.memo() in the child component in the previous case, the Child component did not rerender, although the Parent component did. Nevertheless, passing a function as a prop to a Child ...
In the existing version of React, this problem occurs when the component tree is very large, because the update process is synchronized layer by layer and layer by layer. The process of gradual deepening does not stop until all the components are updated. The function is The call stack is ...

How do you overload in Javascript? There is no way to function overloadingin javascript. So, I recommend like the following by typeof() method instead of multiple function to fake overloading. What is currying and how does it apply to a react application?
