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!

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]

@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);
