F#单位类型

单位类型是指示没有特定值的类型。单元类型只有一个值,当不存在其他值时将充当占位符。

let function1 x y = x + y               

function1 10 20      // this line results a compiler warning
    
// changing the code to the following, eliminates the warning
let result = function1 10 20

// Use this if you are calling the function and don't want the return value
function1 10 20 |> ignore
