Is there any way to perform multiple assignment in JavaScript like this: var a, b = "one", "two"; which would be equivalent to this: var a = "one"; var b = "two";

In python you can do something like this: x,y = 1,2 or x,y = function_that_returns_two_elements() I was trying to do something similar in R but found no solution. Is it possible?

Suppose we have: >>> x = 1 >>> y = 2 If we try assigning both values at once like so: >>> x, y = y, x+y >>> x 2 >>> y 3 Then we get a different result...

I only just noticed that this is valid PowerShell code: PS> $first, $rest = @(1, 2, 3) This statement puts the first item in the array in $first and the remaining items in $rest. PS> $fir...

After reading this and this, which are pretty similar to my question, I still cannot understand the following behaviour: a = 257 b = 257 print(a is b) #False a, b = 257, 257 print(a is b) #T...

I understand that the assignment operator is right associative. So for example x = y = z = 2 is equivalent to (x = (y = (z = 2))) That being the case, I tried the following: foo.x = foo = {a:1} ...

I've come across these variations when seeing multiple variables getting assigned at once: x,y,z = 1,2,3 (x,y,z) = 1,2,3 x,y,z = (1,2,3) (x,y,z) = (1,2,3) I tested these and they all seem to assig...
