Read MoreExamples of How 'text+=""' in JavaScript Work
In JavaScript, the text += "" notation combines the concatenation operator (+) with the assignment operator (=) to append content to an existing variable. This is particularly useful for building strings, HTML content, or any sequential data.

Historically, search engine crawlers like Googlebot could only read static HTML source code and could not scan and index content generated dynamically using JavaScript. This changed with the rise of JavaScript-rich websites and frameworks like Angular, React, and Vue.js, as well as single-page applications (SPAs) and progressive web applications (PWAs). Google has evolved its crawling technology to properly render web pages before indexing them. Although Google can now crawl and index most JavaScript content, they still recommend against relying solely on client-side solutions since JavaScript is "tough to process, and not all search engine crawlers can process it properly or ...
