How to handle protractor test to run in a sequential order

Question

This is my Block which contain an element.element(by.model("$ctrl.benchmark.name")); This is not present on Dom. It give me error that element is not on page but still execute all lines of code written after it. I want this to handle in sequential way if above passes then go to next only. How can I handle these types of problem in Protractor.

it("Test BenchMark",function(){
    browser.getTitle().then(function (name) {
        console.log(name);

        browser.sleep(2000);
        element(by.linkText("Manage Benchmarks")).click();
        browser.sleep(4000)


        //element(by.xpath("//main[@class='ng-scope']//a[text()='Create Benchmark']")).click();
        console.log("megha");
        element(by.model("$ctrl.benchmark.name")).sendKeys("bench");
        element(by.buttonText("Save")).click();
        console.log(megha);
        element(by.xpath("//button[@class='dropdown-toggle']")).click();
        console.log("dropdown clicked")

    });

You can use browser.wait() combined with Expected Conditions.

browser.wait() blocks control flow execution until a promise is resolved, and Expected Conditions all evaluate to a promise.

So in your case, you could use either presenceOf() and/or visibilityOf().

var EC = protractor.ExpectedConditions;
var el = element(by.model("$ctrl.benchmark.name"));
var present = EC.presenceOf(el); // wait for it to be added to DOM
var visible = EC.visibilityOf(el); // wait for it to be visible on page
browser.wait(EC.and(present, visible), 10000); // wait maximum of 10 seconds
// rest of code

The behavior which you are expecting will not be handled by Protractor, it will be by testing framework(ex: Jasmine). But

 "Jasmine doesn't support failing early, in a single spec. The idea is to give     
  you all of the failures in case that helps figure out what is really wrong 
  in your spec"
