Kashish Bansal 39 Explain this in detail
let validExpense = component.find('expenseform').reduce(function (validSoFar, inputCmp) {
inputCmp.showHelpMessageIfInvalid();
return validSoFar && inputCmp.get('v.validity').valid; }, true);
inputCmp.showHelpMessageIfInvalid();
return validSoFar && inputCmp.get('v.validity').valid; }, true);
Greetings!!
inputCmp.showHelpMessageIfInvalid(); this function is used to check if the element is valid or not, if the element is not valid then it will be showing the help message and also the red border around the field which is invalid.
and coming to the third line i.e return validSoFar && inputCmp.get('v.validity').valid; }, true); is basically a if and condition, So in this case, (v.validity).valid , the condition is checking that, the component is in vaid state or not.
