            Description

            
              concat() 
              Joins arrays and returns an array with the joined arrays

            
              copyWithin() 
              Copies array elements within the array, to and from specified positions

            
              every() 
              Checks if every element in an array passes a test

            
              fill() 
              Fill the elements in an array with a static value

            
              filter() 
              Creates a new array with every element in an array that passes a test

            
              find() 
              Returns the value of the first element in an array that passed a test

            
              findIndex() 
              Returns the index of the first element in an array that passed a test

            
              flat() 
              creates a new array with all sub-array elements concatenated into it recursively up to the specified depth.

            
              flatMap() 
              returns a new array formed by applying a given callback function to each element of the array, and then flattening the result by one level.
