and

and(expr, ...)
      

Return false if one of expr, ...s evaluates to false, otherwise return the value of the last expression or true. If no arguments are present, return true.

Note that and is implemented as a macro. So it will evaluate its arguments only if that is required to get the final result.

Examples:

let (x = 3) and(x > 2, x < 4)
// true

let (x = 5) and(x > 2, x < 4)
// false

and(false, 1, 2, 3)
// false

and(1, 2, 3)
// 3
