How to 'continue' inside a each loop : underscore, node.js
node.jsLoopsunderscore.jsnode.js Problem Overview
The code in node.js is simple enough.
_.each(users, function(u, index) {
if (u.superUser === false) {
//return false would break
//continue?
}
//Some code
});
My question is how can I continue to next index without executing "Some code" if superUser is set to false?
PS: I know an else condition would solve the problem. Still curious to know the answer.
node.js Solutions
Solution 1 - node.js
_.each(users, function(u, index) {
if (u.superUser === false) {
return;
//this does not break. _.each will always run
//the iterator function for the entire array
//return value from the iterator is ignored
}
//Some code
});
Side note that with lodash (not underscore) _.forEach if you DO want to end the "loop" early you can explicitly return false from the iteratee function and lodash will terminate the forEach loop early.
Solution 2 - node.js
Instead of continue statement in for loop you can use return statement in _.each() in underscore.js it will skip the current iteration only.
Solution 3 - node.js
_.each(users, function(u, index) {
if (u.superUser) {
//Some code
}
});
