Is it feasible to use if conditions instead of utilizing return when dealing with multiple conditions in our program?
var v2=[12,23,44,3,1,3,456,78,22];
function checkresult(v2) {
return v2 >= 18;
}
var a = v2.filter(checkresult);
document.getElementById("demo").innerHTML = a;
Absolutely, it is possible to utilize conditional statements within a filter as long as the output is a boolean value.
var array=[12,23,44,3,1,3,456,78,22];
function checkValue(value) { // I recommend using a different variable name than array
if(value >= 18)
return true;
else if(<condition-2>)
return true;
else if(<condition-n>)
return true;
return false;
}
var filteredArray = array.filter(checkValue);
document.getElementById("output").innerHTML = filteredArray;
Absolutely, it can be done
function findUniqueItems(value, index, self) {
return self.indexOf(value) === index;
}
var arr = [3,5,'x','z','y',3,'k'];
var uniqueItems = arr.filter(findUniqueItems);
Here in this example code, the findUniqueItems function is used to filter out duplicates and only keep unique values within the array. Feel free to modify the function as needed.
