Categorized request examples and articles tagged with [javascript-array-reduce] keyword How do I reduce an array in JavaScript?
The JavaScript array.reduce(callback, initialValue) method is used to reduce a JavaScript array to a single value by sequentially calling the callback function on each array element and storing the intermediate result. The second optional argument is the value used for the first call to the callback function. If no "initialValue" is passed, the first element of the array will be used. The reduce() method takes the value from the callback function and passes it as an argument to the next call to the callback function. In this JavaScript Array Reduce Example, we use the reduce() method to get the sum of the array elements. Click Execute to run the JavaScript Array Reduce Example online and see the result.
