Hi Dev Community 😇
Did you know that we can actually set our function parameter with a default value, It will make your function at least return default value instead of undefined
, sound great isn't it 🤩
function multiply(a=1 ,b = 1) {
return a * b;
}
console.warn(multiply(3,2))
// expected output : 6 (3 multiply by 2)
console.warn(multiply(5))
// expected output: 5 ( 5 multiply by 1)
console.warn(multiply())
// expected output: 1 (1 multiply by 1)
now could you predict the expected output from this function 🤔
function substraction(a=1 ,b = 3) {
return a - b;
}
console.warn(substraction(3))
// the result is ?
