forEach Array Method | JavaScript Tutorial

thank you for this great explanation <3

I've been hearing a lot of.... distain for the "forEach" method. Especially in the context of asynchronous code.
Not an expert, but be careful using this method.

Hi Florin, can you do a similar playlist of videos as you have for array methods but for strings? Thanks!

thanksss

Thanks a lot. I get it now. I’m currently using ZTM

Nice explanation! It is is exactly that I was after🤓

.

Thanks!

Thank you so much!!!

your code could be done in almost only two lines, but thank you so much.

I found an easier way, const countries = ['Argentina', 'Brazil', 'Argentina', 'Portugal', 'Brazil'];

// Keep track count of every country
let count = {};


countries.forEach((country) => {
count[country] = (count[country] || 0) + 1;
})

console.log(count);

thank you very much for this very clear explanation! it really helped me a lot!!!

if foreach doesnt return anything how can it be used? Thanks

Hi Florin, thanks for your great tutorial. In the end of the video, inside the if parentheses, it's only count[item], normally inside if parentheses would be conditions with comparison operators, so I'm not quite understand what does if (count[item]) stands for, could you explain more for this ?

can you tell me how is your output is showing in the terminal

got yo million yet yo

Hi plss reply me i need help

very good content theacher !!! thaks

let sum = 0;
number.forEach(function(value){
sum += value;
})

console.log(sum);


this would generate the same answer, is there any thing I should know about using it?

Everywhere I read about forEach it says that the method does not return anything but in this tutorial the sum was clearly returned. WUT??? Am I missing something here?

love you florin

Thanks for the Tutorial.

But please can I send you forEach code I wrote that won't work at all? Maybe you can show me what am doing wrong.

For anyone else like me who didn't understand the last Object loop:
The last part if (count[item]) is true if the object has a property and then it goes to the condition of incrementing the property value ++.
If it is false then it's assigned that property with the value 1.

Thank you Sir, your tutorial is very clear and show that we can use the method in different way, thank you so much Sir

This helped me to build a solution for returning a max char from an array. Thnx for this tutorial and whole playlists.

I personally hate Javascript it's so loosely typed, with no structure in mind Garbage!!

You are the BEST... That's the fact

thank you for this tuto , how can i use the terminal like that please

"let count = {}" means that you declare a variable with an undefined value?

Hi, thanks for a great tutorial and I have a small question. How can I get the same result in the terminal - I mean without an unnecessary code (like: $ node "c:\Users\thomas\Desktop\Exercises\script.js"), only pure result, like on your video. Regards, Thomas.

I am thankful to you. Great video.

hey pls help me.... i dnt understand the let count={} and how the count[item]++ works ?
