How to swap 2 variables in javascript

Normally to swap two variables you need a temporary variable because when the first variable is reassigned you lose the value.

leta='apple';letb='orange';lettmp=a;a=b;b=temp;
Enter fullscreen modeExit fullscreen mode

We have the syntax available to perform a swap without need an intermediate variable.

leta='apple';letb='orange';[a,b]=[b,a];console.log(a);// orangeconsole.log(b);// apple
Enter fullscreen modeExit fullscreen mode

Javascript destructuring enable variable swapping without need an intermediate variable.

Cheers mates!
