## Use Destructuring Assignment to Assign Variables from Arrays
|
||
|
|
||
|
We have to take some precaution in this case.
|
||
|
|
||
|
1. No need of const [b,a] as it will keep the effect of assignment local.
|
||
|
|
||
|
2. const [b,a] = [a,b] will result in the value of a,b as undefined(simple assignment rule left to right).
|
||
|
|
||
|
Hence the solution to this problem is
|
||
|
[b,a] = [a,b]
