- Loops: Loops are used to repeat a block of code multiple times. For example, a loop can be used to execute a block of code for each item in a list.
- Optimization: Avoid using inline scripts as they add unnecessary overhead to the website’s code. Instead, use external scripts and compress/ minify them to optimize your website’s performance.
Step 1: Open Developer Tools
Step 2: Find the Element You Want to Edit

h1 element on the page and changes its text content to “New Title”.
