Very good video. Merci beaucoup
i nearly burst out laughing in class when you said that these array methods will "make my life more enjoyable" lol so so true
Its a valuable content that you have shared here
Great❤
What's the difference b/w map, for each, for of, for in, filter could please tell me the differences
Hoping I can get some clarity on how to solve todays Javascriptmas. Array of names, you have to match every name with a partner and can’t be themselves.
Thank you very much
This is wholesome! Clean, Clear and Concise! Props
I personally think that the most must know Array methods are push, indexOf, slice, splice, sort
i am not even into blonds but his videos helped me so much that he is my new crush
Great tutorial, thanks 🙂 👍👍
you should talk slower, the people watching your vids include beginners not just those who need a refresher.
You helped me a lot, i was strungling with this array methods and i can't thank you enough
What laptop do you use?
thanks for this
Thanks a lot bro
I don't find them at all useful except forEach method.
Hello guys, Good day! I started to create a content about JavaScript and other tech stack. I created a short video about JavaScript array includes method. Hope it helps! Thank you!
https://www.youtube.com/shorts/DsnHMhbbP7Y
This simplified so much of the confusion I had around these methods. Subbed!
Finally a simple and objective viedo
Thanks
But wouldnt have includes() also worked on the the json with the names and prices? E.g. items.includes('Book'). Just to check if the book is already in this array?
This video is one of the reasons that I preach people learning sth in this era wouldn't require taking particular courses and having high-paid pedagogues… THANKS SIR♥️♥️♥️♥️♥️♥️
/*
JavaScript array methods simplify complex logic
*/
// filter Method
// Filter method creates a new array based on a condition without changing the original array
// Filter method can be used to get items under $100
const items = [
{ name: 'Bike', price: 100 },
{ name: 'TV', price: 200 },
{ name: 'Album', price: 10 },
{ name: 'Book', price: 5 },
{ name: 'Phone', price: 500 },
{ name: 'Computer', price: 1000 },
{ name: 'Keyboard', price: 25 },
]
const filteredItems = items.filter((item) => {
return item.price <= 100
})
console.log(items);
console.log(filteredItems);
// map Method
// Map method creates a new array by converting each item based on a function
// without changing the original array
// Map creates a new array with the results of calling a function on every item in the original array
const itemNames = items.map((item) => {
return item.name // We can change this to price
})
console.log(items);
console.log(itemNames);
// find Method
// The 'find' method allows for easy retrieval of specific objects in an array
const foundItems = items.find((item) => {
return item.name === "Book"
})
console.log(foundItems);
// forEach Loop
// Using for each loop to simplify array iteration
// Function can be customized to print or perform any action on each element
items.forEach((item) => {
console.log(item.name);
})
// some / every Methods
// The array methods 'some' and 'every' check if any or every item in an array meets a condition.
// 'some' returns true if at least one item meets the condition.
// 'every' returns true only if every item meets the condition.
const hasInexpensiveItems = items.some((item) => {
return item.price <= 100
})
console.log(hasInexpensiveItems); // true
//
const areAllItemsCheap = items.every((item) => {
return item.price <= 100
})
console.log(areAllItemsCheap); // false
// reduce Method
// Reduce method performs operation on array and returns combination of all operations
// Reduce method takes item and property for what to reduce everything into, and a starting point
// Reduce method runs a function on every item in an array and returns a single value
const total = items.reduce((currentTotal, item) => {
return item.price + currentTotal
}, 0)
console.log(total);
// includes
// The includes() method checks if an array has a value and returns a boolean
const numbers = [1, 2, 3, 4, 5]
const includesTwo = numbers.includes(2)
console.log(includesTwo); // true
THANKS A LOT BRO!!! YOU'RE A ROCKSTAR!! 🔥💙
Thank you!
Great content! very insightful!
No fluff, straight to the point! I really thank you for this video!
Thank you
great explanation of array methods in a simple, understandable way. Thank you!
Me, 1:16 in – "Welp, I've been doing THAT the hard way."
Love it 🎉
Home run. Great video.
this may be a simple solution but its one i struggle with, the course i am doing quite frequently requires me to write a function using x method (in this example filter works anyway) i usually start by using the variable keyword, let or const, but then end up just assigning that variable to a function like you do by using .filter() on items. how do i use .filter() on an actual function?
Great examples man! Thank you 🙏
Nice
I watch your videos whenever I want to take a break from regular work and learn something new and interesting. All of these methods made perfect sense when you described them. I'm eager to play with a bunch of these now.
Thank you so much for the clear and concise explanations! 🙂
Great tutorial !!
Thanks
just the best tutor anyone can have
your still the best!
callback function of map takes three parameters 1. Item 2. Index 3. TotalArray
