How to use Javascript executor in protractor instead of sendkeys

sample.js

// Text to be entered
var text = 'My text value';

//  Locator
var input = element(by.model('angularProperty'));

// Now you can use like this
setValue(text, input);

// Using this function
this.setValue = function (inputText, locator) {
	browser.executeScript("arguments[0].setAttribute('value', '" + inputText +"')", locator);
};
