In JavaScript, there is no direct method named contains() for arrays. However, if you're looking to check whether an array contains a certain value, you can use the includes() method, which is commonly used to check if a specific element is present in an array.

Array.prototype.includes()
The includes() method checks if an array contains a specific element and returns true if it is found, or false if it is not.

In JavaScript, the Array.from() method is used to create a new array from an array-like or iterable object. This method can also accept a map function and a thisArg to transform the elements as they are added to the new array.

In JavaScript, the forEach() method is used to execute a provided function once for each element in an array. It's a method that helps iterate through each element of an array, performing an operation on each element without modifying the array itself.

javascript flatmap
n JavaScript, the flatMap() method is used to first map each element using a provided function, and then flatten the result by one level. It's a combination of the map() and flat() methods.

map() transforms each element of an array based on the provided function.
flat() flattens a nested array by a specified level.
flatMap() combines both operations into one.
