What is JavaScript with(o)?

Question

I saw use of a keyword with taking one param in a function, but even documentation on it seems kinda hard to understand. It seems to change scope of an existing variable? Anyone want to give a better explanation?

Answer 1

oh the with statement its a bad thing dont try using it,it digs into an object for its properties.its deprecated.
es6 introduces object destructuring for that.
const {PI}=Math;

Answer 2

obsolete feature, don't use it, like eval

Answer 3

Answer 5

with statement was born for make access to complex/long variable (lexically) in easy way but now its deprecated because add more problems than it remove... Dont use it at all

Answer 6

KrOW it looks like it acts like c++’s using when it comes to the JavaScript Math library, but I don’t completely see what it’s doing with the two param function

Answer 7

you need explore more

Answer 8

Brains🇳🇬 KrOW gave a link to it’s documentation here, it shows it in use, but it only makes sense to me when it makes it so you don’t have to call Math. before every use of PI. I don’t really understand the normal variable stuff with it

Answer 9

Brains🇳🇬 ooo I’ll look into that!
