Understanding currying practically
In this practical implementation, the add function takes one argument x and returns another function that takes the second argument y. This enables currying, as you can call add with one argument (5), resulting in a function that adds 5 to any number passed to it.
function add(x) {
return function (y) {
return x + y;
};
}
const sum = add(5)(3);
console.log(sum);
Output
8
Why is Currying in JavaScript Useful ?
Currying in JavaScript is a functional programming technique that involves transforming a function that takes multiple arguments into a sequence of functions, each taking a single argument. This technique is particularly useful in JavaScript due to its support for higher-order functions and closures, enabling developers to write more expressive and flexible code.
