将参数传递给带有变量的函数或在传递过程中进行修改

Question

While passing parameter to function, there are two ways to pass and i'm not sure about which one is better?

First one is:

const foo = (bar) => bar;

number = 3.4567;
foo(number.toFixed(2));

Second one is:

const foo = (bar) => bar;

number = 3.4567;
fixedNumber = number.toFixed(2);
foo(fixedNumber);

Answer 1

It is basically the same but in the second one you define a new variable for fixedNumber , thus making your code more readable for other developers.
