00:01 Arrays are important data structures used in web development to store different types of data. 01:58 Arrays are a better approach for storing multiple values compared to creating multiple variables 05:49 Arrays in JavaScript can hold multiple values or items of different types. 07:46 Arrays in JavaScript can be accessed by the length property. 11:58 Arrays in JavaScript allow accessing values based on index. 14:02 Arrays in JavaScript can be accessed by index and values can be changed. 18:01 Arrays in JavaScript can be accessed using indexes starting from zero. 19:51 For loops and array iteration in JavaScript 23:52 Creating an array and calculating the sum of its elements 26:00 Using arrays to calculate average marks and apply discounts on prices. 29:59 Using the for loop to track array index 32:12 Understanding how values are copied inside variables 35:58 Arrays in JavaScript have methods that allow us to change the array in place or return a new array. 37:53 Arrays in JavaScript can be used to store and manipulate sets of values. 42:06 Concatenating arrays in JavaScript using the concat() method. 44:19 The unshift method is used to add elements at the start of an array. 48:09 The slice method in JavaScript is used to extract a portion of an array, based on the specified starting and ending indexes. 50:22 Deleting and adding elements in an array using indexes 54:19 Arrays in JavaScript can be manipulated using the splice method. 56:25 Removing and replacing elements in an array

At 31:00 it can also be done by for-of loop. let items = [250, 645, 300, 900, 50]; for (let price of items) { let discount = price * 10 / 100; console.log(price-discount); }

i also did the same way

[@Vatsal74]

If you read the question carefully it suggests to change value of array index. Your solution does provide the correct answer but it does not change the value of array.

[@Vatsal74]

let prices=[100,200,300,400,500,600,700] let j =0 for (let i of prices ){ let updatedPrice= i - ((i*10)/100); prices[j]=updatedPrice; j++; } console.log(prices)
