Is there a way to fully break out of a .forEach loop that's nested within a function?

Question

Is there a way to fully break out of a .forEach loop that's nested within a function?

Here is the method I am currently working with:

    wordFormDirty = (): boolean => {
    var self = this;
    angular.forEach(self.word.wordForms, function (wf, key) {
        var wordFormNgForm = 'wordFormNgForm_' + wf.wordFormId
        if (!self[wordFormNgForm].$pristine) {
            return true;
        }
    });
    return false;
};

I have noticed that this method never returns true. Any suggestions on how to modify it so that a form that is not pristine will cause the wordFormDirty() method to return true?

Do you want to give this a shot? In this scenario, if I'm understanding the issue correctly, when there is a true value for the first time, the result will be set to true; otherwise, it stays false.

wordFormDirty = (): boolean => {
    var self = this;
    var result = false;
    angular.forEach(self.word.wordForms, function (wf, key) {
        var wordFormNgForm = 'wordFormNgForm_' + wf.wordFormId
        if (!self[wordFormNgForm].$pristine) {
            result = true;
        }

    });
    return result;
};

For those looking to obtain a result by walking through the Array, it may be beneficial to explore alternative methods instead of relying solely on the forEach function. Here's an example:

const checkDirtyForms = Object.values(this.word.wordForms).some(
  ({ wordFormId }) => !this[`wordFormNgForm_${wordFormId}`].$pristine
);
return checkDirtyForms;
