Boolean algebra in javascript

Question

Is there any way to use boolean algebra in JS?

Eg I would like to loop through an array containing true & false, and simplify it down to either only true, or false.

Doing it with boolean algebra seems like an elegant way to do it...

[true,true,true,true] //would like to do a comparison that lets me  
//simply add the previous value to  the current iteration of a loop
// and have this return true

[false,true,true,true]//this on the other hand should return false

Answer 1

I think a simple solution would be

return array.indexOf(false) == -1

Answer 2

Try Array.reduce:

[false,true,true,true].reduce(function(a,b) { return a && b; })  // false

[true,true,true,true].reduce(function(a,b) { return a && b; }) // true
