Learn how to use array reduction to create functional pipelines by composing arrays of functions.
const increase = (input) => {
return input + 1;
}
const decrease = (input) => {
return input - 1;
}
const double = (input) => {
return input * 2;
}
const halven = (input) => {
return input / 2;
}
let pipelines = [
increase,
increase,
decrease,
double,
halven,
increase
];
let init_value = 1;
let res = pipelines.reduce( (acc, fn) => {
return fn(acc);
}, init_value );
console.log(res);
