Anjana Vakil: Immutable data structures for functional JS | JSConf EU

Functional programming has been gaining a lot of popularity in the JS community, and with good reason: rejecting side-effects and mutability - in-place changes to data - helps avoid a lot of headaches. But when you refuse to mutate objects, you have to create a whole new object each time something changes, which can slow things down and eat up memory, making functional programming seem inefficient.

That’s where immutable data structures come in - to save the day, and time and space! Also called “persistent data structures”, they help you efficiently make new “modified” versions of immutable objects, by reusing parts of the old object that you don’t need to change.

Came here from her unconf 2016 video . i need more of her talks .

[victorpetrescu]

Nice talk. She has a cool way of making even things you already understand/know more clear (and fun). And definitely more energy than last 10 talks I've been to. Wish more speakers would be a bit more like that.

Anjana vakil, you are awesome ! ...please make your own channel !!

[CerdasIN]

Very talented. She can bring programing more informative than before. Technical but easy learning. Thanks..

[AlwinArrasyid]

The way she explains things is really something.

[ThePsyrencall]

Fantastic introduction to how immutable data structures are represented under the hood! Good job!

[monugupta]

The way she talks, it's too good !

¡Muchisíma gracias!
Danke schön!
Wielkie dzięki!
Thank you very much!

This is so on time. I was just learning about immutability in FP. Great talk

[normanlipkow]

Thanks again Anjana! You got me hooked to functional programming. Really good and informative talk.

"Immutability rocks like rocks rock."

[vmvini]

Wow! A quote from 'I heart huckabees'. Loved

[nueythepyasuwan]

Informative and well delivered talk. Thank you!

[stardust]

Nice talk.
Those in hurry, skip to 8:55.

[AndricLibreSinn]

This was/is an excellent talk. I'll try to implement some of this in my own for learning.

[chauhan]
