    Currying is a technique in functional programming where a function with multiple arguments is transformed into a sequence of nested functions, each taking a single argument.

    • Currying helps in creating reusable functions and partial application.

    • It allows you to create new functions by fixing some parameters of an existing function.

    • Example: const add = (a) => (b) => a + b; add(2)(3) will return 5.

    • Filter returns a new array with only the elements that pass a provided condition function.

    • Example for Map: [1, 2, 3].map(num => num * 2) will result in [2, 4, 6].
