Tagged Template Literals

Template literal strings are great for embedding (interpolating) variables and expressions inside JavaScript strings.
They also include a feature called tagged template literals that let you create a function which will give you granular control over all the strings and expressions inside the template string.

i don't know why you and dcode has far less subscribers although you both are among the best ! Thank you for the effort you put into this. keep up the amazing work!

I love your content. Your content has improved me a lot♥️♥️

Hey Steve. You make some damn fine content, really really excellent.

Now (3 years after the video was posted) there's a pretty neat feature `String.raw`. It helps simplify the function at 10:25 to a one-liner: ``` const f = (strings, ...values) => String.raw({ raw: strings }, ...values.map(i => i.toUpperCase())) ```

[@SteveGriffith-Prof3ssorSt3v3]

I should add String.raw to my video todo list and talk about what it can and can't do.

[@rebelmachine88]

Had NO clue about this one. Very helpful video, thanks!

This is a great way to make html templates using vanilla js. It's what I've been using and it works 👍 Tips: 1. Replace null valued variables to empty strings. This will allows you to do conditional rendering similar to react using the && operator. 2. Join array variables automatically so you can render looping template (cards, table rows, etc.) cleanly. 3. Use "html" as your tagged template literal function name so vscode extensions will pick it up and format them as html.

Very good Explaination. Thanks

[@rohanbaikar]

Can you give more examples or provide a link or something inorder to have a more clear idea of how to implement this concept its sure interesting though

[@joaovaz3473]

Check out MDN (Mozilla Developers Network) page on tagged template literals, it always has cool examples on its documentation

[@paulofernandoee]

Great video! Thanks.

Hey steve great contents. So here comes the weird suggestion. Have you ever thought about doing a voice over work or reading an audio book? I just think you should at least look in to it. You have a great voice. Any way i love your javascript lessons thank you for making videos.

[@SteveGriffith-Prof3ssorSt3v3]

I have considered it and discussed it with another voice actor I know. Just a matter of having the time to do it.

[@MrKelbessa]

Steve Griffith Good luck Sir, I’m rooting for you

[@bruhmoment3731]

Gosh you have a great voice!

[@demiancoorey2394]

Excellent explanation

[@silentstorm8470]

im back again to ask look at this code (i couldnt understand how the keys and value of the objects are passed as parametres on the function) this is the code: const user = { id: 101010, name: "Derek", email: "[e-mail]" }; function replace(key, value) { if (typeof value == 'number') { return undefined; } if (key == 'email') { return ' remover for privacy'; } return value; }; //when i console this how does the keys and values from user object are used as parametres in replace function??????? console.log(JSON.stringify(user, replace));

[@SteveGriffith-Prof3ssorSt3v3]

This video is about tagged template literal functions, not JSON.stringify. They are different things. kzbin.info/www/bejne/ZpyXf6qfosumsKM - here is my video on stringify.

Thanks for putting the effort to make this video. This is the first time I know about tagged template literals. Also, you sound a bit like a calmer RDJ 😁

[@theoligarchist1503]

cool, looks like a boon for generated JS , generated from other Languages :-)

Rewatching this video after 7 months. I love the pace.

trying to understand this on mdn was a nightmare, thanks Professor Steve!

[@howiewang4238]

Thank you for this tutorial. It helped me.

[@ariyaman90]

Hey Steve! Thank you. That was very very understandable

[@techlover1219]

Thank you again. I have a question about the template literal.. When i am using template literal to print a object it is showing [object Object]..but when i am using the traditional way, it is showing the value of the object. Please explain the reason of this behaviour.

[@SteveGriffith-Prof3ssorSt3v3]

You must embed a specific object property ${myObj.prop}. If you just try to embed the whole object ${myObj} then you will always get [object Object] because it just does a conversion to String. The String equivalent of EVERY object is [object Object]. This is why you can't use Objects as a keys inside other objects. Every object key must be a String or a Symbol.

[@chesterxp508]

Another very cool tutorial!

[@Lior621]

Such a clear explanation! thank you 😍

[@devkushwaha6682]

According to your Time there I think 4:00 am right now, brother you are making video at that time

[@SteveGriffith-Prof3ssorSt3v3]

I schedule the release of my videos. Many of them at 4am UTC.

[@chyldstudios]

Clear and to the point!

Thanks, steve how do i get the coordinates appear in real time(updated with little change in position)

[@SteveGriffith-Prof3ssorSt3v3]

What coordinates? I'm talking about template strings and functions here.
