dynamic if condition comparison of variables in javascript

I've 3 variables a,b,c

The initial values of this variables will be 'false'

I want to compare this variables only have that 'true' value.

For example, 

a=true,b=false,c=true.

So I need to compare like,

if(a && c)

if, a=true,b=true,c=true,

if(a && b && c)

How can I generate this if condition dynamically?

I suppose you could approach the issue with [].every() which performs a similar comparison:

if ([a, b, c].every(Boolean)) {
    // etc.
}

Here, Boolean() is a native function that will accept a value and return its boolean value.

That said, just this will cover all cases too, considering that it uses short circuiting to stop the comparison once a false value is found and is undoubtedly easier to read:

if (a && b && c) {
    // etc.
}
