TypeError: map is not a function | Error in React solved 2024

hello guys so in console you can see I'm getting this type error map is not a function so in order to solve this you have to go to this uh file uh I have this on line number 30 to 40 so let's go to vs code and here in line number 30 to 40 you can see I have used this map function uh I have set this post State and initially I have given this MPD array and after getting data from API I have set this data but it is not working so in order to solve this what you have to do you have to just add placeholder here so basically what it does it will only run this code that is map function if uh the post is not null or undefined so you have to use this placeholder before using this map function you have to check if it is array or not so use this method and inside this method you have to pass the array so after that you have to use and operator and save this code so now this map function is only going to run if this post is an array so after this you can run your application thanks for watching
