Go to "next" iteration in JavaScript forEach loop [duplicate]
How do I go to the next iteration of a JavaScript Array.forEach()
loop?
For example:
var myArr = [1, 2, 3, 4];
myArr.forEach(function(elem){
if (elem === 3) {
// Go to "next" iteration. Or "continue" to next iteration...
}
console.log(elem);
});
MDN docs only mention breaking out of the loop entirely, not moving to next iteration.
You can simply return
if you want to skip the current iteration.
Since you're in a function, if you return
before doing anything else, then you have effectively skipped execution of the code below the return
statement.
JavaScript's forEach works a bit different from how one might be used to from other languages for each loops. If reading on the MDN, it says that a function is executed for each of the elements in the array, in ascending order. To continue to the next element, that is, run the next function, you can simply return the current function without having it do any computation.
Adding a return and it will go to the next run of the loop:
var myArr = [1,2,3,4];
myArr.forEach(function(elem){
if (elem === 3) {
return;
}
console.log(elem);
});
Output: 1, 2, 4
just return true inside your if statement
var myArr = [1,2,3,4];
myArr.forEach(function(elem){
if (elem === 3) {
return true;
// Go to "next" iteration. Or "continue" to next iteration...
}
console.log(elem);
});
