re: JavaScript: Reduce the number of conditional operators used in the expression VIEW POST

Hi @kvharish , I like what you are trying to do, however wouldn't it be better to make use of the array functions like every or some?, that way you eliminate the need for an additional function:

const firstCondition = true,
  secondCondition = true,
  thirdCondition = true;

const conditionArray = [
  firstCondition,
  secondCondition,
  thirdCondition
];

if (conditionArray.every(contition => condition)) {
  console.log("All the conditions met expectation");
} else {
  console.log("All the conditions did not meet expectation");
}

if (conditionArray.some(condition => condition)) {
  console.log("Atleast one of the conditions met expectation");
} else {
  console.log("None of the conditions met the expectation");
}

And just because I love lazy evaluation you could even turn those conditions into predicates:


const firstPredicate = target => true;
const secondPredicate = target => true;
const thirdPredicate = target => true;

const predicates = [firstPredicate, secondPredicate, thirdPredicate];

conditionArray.every(predicate => predicate(obj))

That way conditions are not evaluated until you need them to.

Regards

 

Definitely agree using every and some are the way to go. You could simplify further by using Boolean like so, conditionArray.every(Boolean)

 

Nice, haven't tried it, however, won't it evaluate as true for Boolean being an object?
