How to use a return value in another function in Javascript?

rated 0 times [ 89] [ 7] / answers: 1 / hits: 127884 / 11 Years ago, wed, october 30, 2013, 12:00:00

I'm self-teaching myself JavaScript and out of curiosity I'm wondering what is the proper way of returning a value from one function to be used in another function. For example:

function firstFunction() {

  // do something;

  return somevalue 

}

So how do I set up the second function to use somevalue? Thanks.

Call the function and save the return value of that very call.

function firstFunction() {

  // do something

  return testing 123;

}



var test = firstFunction();  // this will grab you the return value from firstFunction();

alert(test);

You can make this call from another function too, as long as both functions have same scope.

For example:

function testCase() {

  var test = firstFunction(); 

  alert(test);

}
