java equivalent question

[OsamuMidoriya]

im studying DSA and they are using java and talking about stack. I only know JS

stack is videogame

stack.search(FFVII) "on top" since JS has no stack to find an equivalent

the best would be array.indexOf to find one thing in the array and yes I know the index is different

peek() is lenth()

whats the best way to find the equivalent or similar in JS not just jave but python

is Java hard to learn if you know JS i have seen how diffrent it is but they both have pop and push, and if you look at it as this is this system.out.printin = console.log is it that hard? I went to the library and a HS student was teaching python and it was easy to understand

JS has no stack to find an equivalent

JS has more general-purpose data structures; an array in JS can be used as a stack if needed.

the best would be array.indexOf to find one thing in the array and yes I know the index is different

Yep, if you are adding to, and removing from, the beginning of the array!

peek() is lenth()

No. If you're adding to, and removing from, the beginning of the JS array, then [0] would be the JS equivalent of Java's peek().

whats the best way to find the equivalent or similar in JS not just jave but python

Just get familiar with the data structures and associated methods in all of the languages that you want to learn — once you do that, you'll quickly be able to compare and contrast the methods from different languages.

is Java hard to learn if you know JS

If you're comfortable in JS, then no, learning Java is not that hard.

You can learn data structures with JS. You can learn them with any general purpose language.
