WebElement img = driver.findElement(By.id("abc"));

Answer 1

попробуйте это:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
   withCapabilities(webdriver.Capabilities.chrome()).
   build();

driver.get('your URL');  
//WebElement img = driver.findElement(webdriver.By.id('abc')); 
// We can't use `WebElement` at here, in javascript, 
// we can't declare the type of variable like Java.
// In your case, JavaScript will treat `WebElement` as variable name,
// Because there already has a variable name, JavaScript don't know 
// how to deal with the following `img`.
// You should change `WebElement` to `var` or `const`

var img = driver.findElement(webdriver.By.id('abc'));
