Is setting multiple variables in 1 line valid in javascript? (var x=y='value';)

Question

This is valid in php:

$x=$y=\'value\';

This will in esscence set both $x and $y to \'value\'.

Is this valid in javascript?

Answer 1

To prevent the y from becoming a global variable, use the following:

var x, y = x = 'value';

Apparently the declarations are simply evaluated from left to right.
