React Array Functions-
This array method is widely used on React to reduce the elements present in an array into one. It can’t access the index or the current value of an array and instead just utilises its previous value. Two arguments are accepted to perform an action and the return can be an object, integer, string, or array. The two parameters are called current value and accumulator. The callback function runs one time lesser than the total length of the array.
An array function of React that is not so well-known, the every() function can be used to check if the elements present in the array adhere to a given condition that is passed in the parameter by the developer. The return value is boolean where if all the elements follow the condition, the return value is a ‘true’ and if not, it’s ‘false’.
Many other array functions are available in-built on React and are utilised for many reasons like React lists need the map() function.
