Imagine you have a bunch of toys in a basket, and you want to do different things with them: 1. Map: Imagine you want to paint each toy in the basket with a bright color. To do this, you would take one toy at a time, paint it, and put it back in the basket. Map works similarly. It takes a function and applies it to each toy in the basket, creating a new basket with the transformed toys. So, map transforms each toy without changing their order or number. 2. Filter: Now, let's say you only want to keep the toys that are soft. You would go through each toy, feel its texture, and keep only the soft ones in the basket. Filter works in a similar way. It takes a function that checks a condition and applies it to each toy. It creates a new basket containing only the toys that satisfy the condition. So, filter helps you select and keep only specific toys based on a condition. 3. Reduce: Finally, imagine you want to find the total number of toys in the basket. You would count one toy at a time, adding the count to a running total. Reduce does something similar. It takes a function that combines two toys and reduces the collection to a single value. In our case, it would add the count of each toy to a running total until there are no more toys left. So, reduce helps you aggregate or combine values into a single result. I hope this simplified explanation helps you understand the concepts of map, filter, and reduce!
Bhai mere pass laptop nhi h fir v Python , html ,css , C sikha hoon haryy Bhai se phone se code krke online compilers and interpreters ke through. Or avi replit se krte h coding iss JS course ko. Thank you Harry bhai.🤟✨
Excuse me sir ! Ye problem samaj main nehi aa raha 🙏🏻🥺.. 7:6 yaha pe function name a ko kese pata ki a array ka values le raha hain ( array ka naam to alag hain na == arr
@@bhaskarartwork5762 Bcz 7:06 py a2 ko arr2(array) KY equal kiya aur usmy (a) likha tou ab wo as (a) use ho rhi hai "array"...isliya wo array ki values Lai Raha..
perfect explanation Harry bhai....map ko main pahaaar smjh raha tha ....ap ny to aisy explain kr k smjhaya jesy koi makhi urra di ho.....❤❤...Thank you so much brother
@codewithharry; bhai apki puri series nhi dekhi but jis jis topic me doubt hai vo dekha, sachme eakdum clear ho gya. The amount of hardware you put while creating this and explaining is commendable and should be appreciated. Thankyou!
These series are extremely helpful. I have a small request for you. After finishing this tutorial please make a full tutorial on the integration of React app inside WordPress. Thank you so much.
A little bit of Motivation from my side : Got infected by Denguee , couldn't code for 2 months and now after 1 month practice , i am back where i left , i watched your html video did html project , watched your css video did the project and now i'm back where i left (Nov 19 to Dec 16) and now i will end this playlist as well
Hi Harry, I am Jawad Azeemi from Pakistan; just started learning from you instead of my instructor because he is worthy to teach but at the same time, you too worthy because you run with new values added day by day in JS. Thanks. // let luther = [45, 87, 4, 65] // luther.map((value)=>{ // value ke jagha kuch be likh sakte ho aap log // console.log(value)// jo value ya kuch ooper likha ha , wahi idher be likhna ha // }) let luther = [45, 87, 4, 65] // ab ham thora change kerte han ooper walay ko let flower =luther.map((value)=>{ return value + 2 // console.log(value) }) console.log(flower) /* now ma chahta hoo ke ye 2 sirf aur sirf add ho index 2 ka sath jo ke array ma 4 ha*/ let luther1 = [45, 87, 4, 65]; let flower1 = luther1.map((value, index) => { if (index === 2) { return value + 2; // Adds 2 only to the element at index 2. } else { return value; // For other elements, keep the same value. } }); console.log(flower1); // Output: [45, 87, 6, 65]
Thank you harish sir you are such a great teacher love you sir ❤️❤️❤️❤️ I am watching your old video for learning I am BCA student of secend year starting
Love u bro 😂❤❤ whenever i see you i feel relaxed but kbhi kbhi apki speed ke barabar ane me time lag jata hai lekin kam mt krna yahi sahi hai speed revision ke liy best h
Thank You Harry Bhai I searched map,filter,reduce but I couldn't understand I was just waiting for your next video.Higer Order Function, Really Helpful Course Thanks Alot.
12:10 bahut bada concept lugta tha map , filter , reduce ; bahut advance concept lugta tha in fact intimidating bhi lugta tha mujhey toh lekin such bataun harry bhai , aap ki video dekhne k baad samjh mei ayaa ki ye kya choti si cheez se durr ruha tha mei . Thank u so much complicated ko simple bananey k liye ! Happy Diwali !🪔

@CodeWithHarry // Reduce() returns single value from array and used to perform operation on the elements of called array like here we are multiplying elements from the called array and returning the output. // If we provide three argument to the reduce() then the 1st and 2nd arguments will be elements of the array and 3rd argument will be the index of 2nd element in the operation. let arr3 = [1, 5, 6, 4, 3, 2]; let a3 = arr3.reduce((d1,d2)=> { return d1*d2; }); let a4 = arr3.reduce((d1,d2,d3)=>{ return d1*d2*d3; }) console.log(a3); console.log(a4);
Hey Harry, You did a great job. And "Thanks" is very small word for all of your efforts. I believe "God Bless You" will be more apprepreate for your cpntinous endless efforts.
00:02 Learn about Map, Filter, and Reduce 01:50 Exploring the differences between map and forEach in JavaScript 03:23 Map creates a new array and foreach iterates over and does something for each array element. 04:49 Use map method to create a new array with values from original array 06:21 The filter function in JavaScript filters an array based on a given condition. 07:53 The reduce method in JavaScript 09:26 The reduce function takes the first and second values and runs the same function with the result 11:05 Map, Filter, Reduce is a modern concept Crafted by Merlin AI.

Filter function me agar humein practically dekhna hai k changes existing array me ho rahi hain to ap ye code run kar k dekh sakty hain. let k sath nhi ho sakta check. var arr2 = [ 2,3,5,10,15,20] var arr2 = arr2.filter((a)=>{ return a
In reduce we can paas initail summation ..like here i am passing -1 . let num=[1,2,3] let sum = num.reduce((prev, curr, index, array) => { return prev + curr; }, -1) Guess the output.
Harry brother please make videos on DSA with javascript parallely I know it will be very tough to make but I really want and it will also help others 🙏
