Value vs Reference in JavaScript in 1 Minute

Full video: • JavaScript Value vs. R...
JavaScript Copy by Value vs. Copy by Reference.
This is episode 10 in a 10 part series I’m calling 10 things javascript. Today for episode 10, we’re looking at the difference between Primitives and Objects. Episode 10: Value vs. Reference. Let’s go!

Nice

[@sk8ns4life]

Some of the better short form dev content I've come across.

[@boem231]

Technically null is an object, but it goes by value. typeof null === 'object'. And NaN (not a number) with the type number, is a primitive, but goes by reference. So there are a few exceptions to this rule

[@UrekMazlno]

I love your youtube shorts. One thing I would suggest though is put the link of the full video in the comments so it can be readily accessible.

[@ColorCodeio]

Good suggestion 👍

[@hamadsherazi6896]

I loveeeeee thus content boy

[@hadawardgz]

Fun fact: *typeof* keyword is broken and says *null* is a object tho it's not, u can't assign properties to null. *typeof null === "object";* // true

[@trivedi2690]

So how can we check this thingh .

[@Venaber]

Thanks

[@gdmathguy]

I have dealt with that in a game I'm programming. Isn't that hard to fix the addressing problems

[@Tanner_Goodale]

Could you create a checksum of two objects by hashing them and comparing their hashed values to determine equality? That's the first thing that comes to mind for me, though I'm sure there are more efficient ways to handle it.

[@soniablanche5672]

One funny suggestion is to use JSON.stringify to compare 2 objects, but this won't work if the objects has functions in them.

[@abdulrasheedibrahim382]

Technically, everything in JavaScript is an object.

[@lex-zt6uc]

Had a question If thier is a object like a with value 5 And b with a value 5 too So does both refer to a same place And if it does will changing b affect a?

[@tjtechi4448]

very great content, video editing and overall presentation. But please remove the background noise. Thank you. I just found out about your channel and it's a great ride so far.

[@ColorCodeio]

Thanks

[@sulaimanatayi555]

nice

[@mitkomilev4690]

Aren't symbols primitives too? And bigInt 🤔

[@juanpablocastrohurtado2088]

is it possible to print the memory reference from an object?

[@alext5497]

Lol

[@hardiknadiyaparanadiyapara7635]

👍👍👍

[@samuelbuer8683]

Thanksgiving ❤

[@ColorCodeio]

Same to you!

[@florinflorin2877]

string and numbers are definitelly not primitives in js, these are objects too (you can extend them, call functions on them)
