In the example above, an array of names is defined and assigned 3 values: Amy, Industry Email List Bruce, and Chris. Then David is added to the list using the push(). With modern reactive frameworks, mutating values ​​can trigger 'diff' evaluations of a page DOM Industry Email List against a newer 'virtual DOM' by the framework, and because the array values ​​differ, the page values ​​can be updated by JavaScript without reloading the browser window. Responsiveness in web applications is where JavaScript has really added to our capabilities, and where our capabilities Industry Email List continue to advance as modern JavaScript further evolves on the server Industry Email List and in the browser. It becomes difficult to keep track of JavaScript written for the server versus JavaScript that is shipped to the browser. For example, with ES6 you can do the following, including the ability to use 'let' (and 'const') in Industry Email List set statements: <script> leave the names = [ "Amy", “Bruces”, "Chris" ]; names = [...names, 'David']; </script> Backwards compatibility The name array mutation above uses a new “spread operator” syntax [...names]to represent the current values ​​of the name array, then adds David using an assignment Industry Email List operation instead of the push() method. The new syntax is not compatible with Chrome 41, so would not work until Googlebot was updated to Chrome 74. For developers, it's like death by a thousand Industry Email List cuts to have to write or transpile ES6 to the low for backward compatibility. Now most of the modern JavaScript syntax will start working directly with Googlebot and there are literally dozens Industry Email List of new features available such as the one above. Just be aware that Bing and DuckDuckGo (as well as social share crawlers) may not be able to interpret ES6 syntax.
