Check positive / no

Question

How can I check the positive number in Javascript and return the opposite?

Example, pass to a function or enter into the prompt:

1: -1 14: -14

UPD: the code turned out to be with an error - plus changed to negative now changes as needed

  function opposite(number) { if (number < 0) { return -(number) } else { return +(number) } } console.log(opposite(-1));

I solved the problem as best I could, then asked for help from the community, with the goal that the more experienced comrades offered a simpler and more universal solution

 function opposite(number) { if (number < 0) { return Math.abs(number) } else { return -Math.abs(number) } } opposite(700) //output -700

For reference: Math.abs ()
