Here's the assignment to print the newMap : for (const [key, value] of newMap.entries()) { console.log(`${key} = ${value}`); } Loving this course Sir :D for (const video of javascript.videos()) { console.log(` ${video}`); }

Sir, Your content is one of the simplest and sorted content in YT. It's really great to learn from you.

@ManishSharma-iv9po 5 лет назад

Sir, I was that person who really got afraid when I saw coding seriously I didn't like it . But somehow I want to learn it. The way you teach is really amazing and now I am loving to code. This can happens only because of you. Thanks for such a wonderful content and the best part is the way you teach is amazing.

@sahujiofficial7834 5 лет назад

Fall 🍁🍂 in love with with your all course videos But have fear about Linux installation... 🙁 thank u again sir and looking for all upcoming free video courses series u tell everyone why we should and to what learn..

@udaypavan4654 5 лет назад

At last, what you told , converting arrofarr to map will only work for if we give only two elements in each array(out of which first one is key and second one is value). Of-course map is considering only second element in array as value. It's not bothering about third and so on. Am I right ??

@aadityashrivastava8105 6 лет назад

Another great video of your Awesome JS Tutorial series. I am in love with this series. Great work and keep it up 👌🏻🤘🏻.

@amanshelar7987 5 лет назад

let Mymap = new Map(arryofarry) for([key , value] of myMap.entries() { console.log( `${value} = ${key}` ) }

@subhranil764 6 лет назад

You make it super easy😊

@vikillakkavatri4070 6 лет назад

Yes sir, its really help me thanks sir .

@mykravtsiv13 4 года назад

hey everyone, thanks for video - to the author! I really have no explanation: ??!! what's wrong with these results -Here it happened when for-of loop was being explained. So here it is : when the console.log is used ( in browser console !) and is written this way - in single line: console.log(key + ' = ' + value ); >> RESULT is displayed with 'Object object' > RESULT is same in first line, but OBJECTS in THE 2nd LINE - CAN BE OPENED now. .. What's changed??? Must be some simple thing, but it looks pretty mystic for me, I meet this ALWAYS in BROWSER's console...And this is NOT just a useless thing !!! - I have always to write all console.logs in TWO lines - everywhere when checking code ! It is so many additional loines! Any ideas ?...

@rahulmotwani1071 6 лет назад

Sir, the thing which I found that can it be possible to cut down the price of the courses because as a student it is really difficult to manage that cost. Please if possible to do may be it can be better for everyone.

@yuganshdwivedi4331 6 лет назад

@anjanidhiman 6 лет назад

It's too good, but sir if you tell us how to use maps in real projects, then it will become really helpful.

@riefkymaulana9040 6 лет назад

is the assignment 'convert the above line in literals ' means that we explain how the code work with our words?

@DormantIdeasNIQ 4 года назад

It is sad that the NOSQL setups are going to become obsolete. They are a bad idea gone bad. Go to SQLite instead. I cannot remember the article that cleared this up, but it left no doubt.

@crazyfm6312 6 лет назад

@georgenjue7197 5 лет назад

Am from Kenya thanks a lot am I right on the assignment on this specific assignment ? my solution is newMap.forEach((value, key) => console.log(key + ' = ' + value.name));

@hardik.motwani 5 лет назад

Even if i use newMap instead of newMap.entries(), i am getting the same result, So what is the need for entries()?? Please explain me var arrofArr = [['One', 1], ['Two', 2], ['Three', 3]] var newMap = new Map(arrofArr) console.log(newMap) for (const [key, value] of newMap.entries()) { console.log(`${key} = ${value}`) }

@neonemesis8055 6 лет назад

@vineetbramhankar8099 5 лет назад

@nguyenquan4836 5 лет назад

@amitnegi6493 6 лет назад

var arrofArr = [['one', 1], ['two', 2], ['three', 3]] var newMap = new Map(arrofArr) console.log(newMap.keys()) This prints all the keys like 'one' 'two' 'three' but when i try console.log(`${newMap.keys()}`) it rather prints [object map itreator]. Can you please tell me why? These are some log statements that does not print valuable information: console.log(newMap.keys() + ' = ' + newMap.values()); console.log(`${newMap.keys()} = ${newMap.values()}`); Explanation Required for these statements too.

@Rishabhgupta-cz7ym 6 лет назад

you have to use for of loop for printing each iterator, just try this it will work --- var arrofArr = [['one', 1], ['two', 2], ['three', 3]] var newMap = new Map(arrofArr) for(const [key, value] of newMap.entries()){ console.log(key + ' = ' + value); console.log(`${value}`) console.log(`${key} = ${value}`); }

@mujtabam265 6 лет назад

@hardik.motwani 5 лет назад

sir where is video of iterators and generators? Is that in this series

@amishaa9555 6 лет назад

can someone please tell me what does he mean by string literals!!!! like i cannot understand his assignment properly

@prasoonpandey1184 6 лет назад

Me too :/

@riefkymaulana9040 6 лет назад

maybe we explain how the code work with our words

@chetangupta8806 5 лет назад

string literal is the string value which is stored

@hometv4061 3 года назад

“Literal” simply means that it's the value itself, rather than a variable. ... For example: const dog = 'Santa's Little Helper'; Santa's Little Helper is a string literal, whereas dog isn't.

@mohinijadhav5985 5 лет назад

Hey where is your try catch session ??? in your ../01advance folder there is one more file for trycatch.js where is that session

@hardik.motwani 5 лет назад

complete list of video is available on Learncodeonline website, you will find all videos there

@abhayrajsingh777 5 лет назад

you have not uploaded try catch video in the series.....please upload it

@ruhankhandaker5198 6 лет назад

These videos takes time to prepare content, putting up best possible example, recording, editing and publishing. Also my goal is that students should be able to repeat what I am doing.
