Key takeaways from the video:-
To compose two functions accepting two arguments, following can be done:-
function composeTwo(fn1, fn2){
return function(a, b){
return fn2(fn1(a, b));
};
}
In ES6, the same can be written as, const c2f=(fn1, fn2) => (a, b) => fn2(fn1(a, b));

and for composing unlimited functons, we can do the following:-
function compose(...fns){
return function(...values){
return fns.reduce( (a, b) => b(a), value);
};
}

Great Explanation, I mean Effortless, You are Natural bro

[VarunMalik-momr]

Bhaiya you’re best the way you narrate these complex concepts in a story way hats off❤️

[jaigangemata]

ohhh! I am just a beginner, who was following your series, but this is the only lecture which has gone total parabola over my head. Shit! JS is

😏You Did Not Taught Us Well...

8:56 You Got Stuck...Where You Used reduceRight...

and After It You Cutted Your Video

And Solved By Making It "reduce" function... and you didn't even Mention About It...

This Is Where I Also Stuck And THinking Why Your Code Is Working And Mine


At Least Smjana To Chye Tha Ki Kyu Erroor Aa rhi thi aur kyu reduceRight Function ki jgh reduce function ka use karna pda....










Sorry, , , But You Are Teaching Next Level, , , , But I Have Head Ache rn. so please Give Answer The My q's.... if possible 🙏🏼❤

const canFly = (obj) => ({
...obj,
fly: () => console.log("Flying high!"),
});

const canSwim = (obj) => ({
...obj,
swim: () => console.log("Swimming deep!"),
});

const bird = canFly({ name: "Eagle" });
const fish = canSwim({ name: "Shark" });

bird.fly(); // Output: "Flying high!"
fish.swim(); // Output: "Swimming deep!"

[amankumarsharma]

can't we write like this ? type Add = (a:number, b:number) => number
const add:Add = (a, b) => a+b
type Square = (a:number) => number
const square =(a) => a*a
const flow = (f, g) => (x, y) => f(g(x, y))
const add_then_square = flow(square, add)
console.log(add_then_square(2, 4))

in functional programming first we should define the type of each method, each variable .

[mohammedshahed]

Bhai Square function is supposed to square a number not multiply any two numbers!
