Yes, you can also use any alternative onload event, i recommend to read something about. Also, you can omit an onload event and put all your code after the <body> in a <script> tag, not the best practice. Also, you can omit an onload event initializing global variables after the <body> in a <script> tag and put your main content elsewhere, maybe adding event inside tags, such as: <body onclick="func()"></body> The best practice is separate the HTML content from the JS content and use an onload event. In your environment you can put the <script src="file.js"> after the <body> element, in Sololearn (until you use an external source) you can't, CodePlayground uses tabs!
