Why do we return more than once

JavaScript
1

Hi,

I am on functional programming on JS course in FC. One thing that confuses me is when to return more than once? take for example my code:

function checkPositive(arr) {

return arr.every(function(element) {
return element > 0;
});

}

is there a better way to understand when to use the return statement more than once and and the logic behind when how you know?

thanks

log things to see what is happening. for example:

function check(arr) {
console.log('started func')
return arr.every(function(e) {
  console.log(e);
  return e < 10});
}
console.log(  check([1, 2, 3, -4, 5]) )

change the test to see what happens, eg: e>=0 or e=5

or

function check(arr) {
  let testLog = false
  testLog =  arr.every(function(e) {console.log(e);return e < 10})
  console.log('inside testLog:',testLog)
  return testLog
}
console.log( 'result:', check([1, 2, 3, -4, 5]) )

or look at it like this:

function check(arr) {
  function test(e) {
     return e >= 0;
  }
  const testLog = arr.every(test)
  return testLog
}
console.log( 'result:', check([1, 2, 3, -4, 5]) )

or:

function test(e) {
  return (e > 4);
}

function check(arr) {
  const testLog = arr.every(test)
  return testLog
}

console.log( 'result:', check([1, 2, 3, -4, 5]) )
