Example Of Javascript Reduce With An Array Of Objects Codevscolor The reduce () method of array instances executes a user supplied "reducer" callback function on each element of the array, in order, passing in the return value from the calculation on the preceding element. the final result of running the reducer across all elements of the array is a single value.
