Breaking out of a Protractor .filter() or .map() loop

You are returning a single element, so .reduce would be preferable.

Here is a usage example to return the first link where the text is "mylink":

var link = element.all(by.css('a')).reduce(function (result, elem, index) {    if(result) return result;    return elem.getText().then(function(text){        if(text === "mylink") return elem;    });}).then(function(result){    if(!result) throw new Error("Element not found");    return result;});

What i understood from your post is, you would like to exit loop(iterate) when find a match element.

If yes, then better go with .filter() method. As it iterates on all available list of element finders and returns when a match finds.

Code Snippet:element.all(by.css('.items li')).filter(function(elem, index) {          return elem.getText().then(function(text) {                                if(text === 'RequiredElementFind'){                                      return ele;//return matched element                                 };    });}).click();//only matched element comes from the loop do what would you like      to do
