JS - Measuring JavaScript Functions’ Performance

Performance has always played a crucial part in software. On the web, performance is even more important as our users can easily change website and visit one of our competitors if we offer them slow pages. As professional web developers, we have to take this issue into account. A lot of old web performance optimization best practices, such as minimizing requests, using a CDN and not writing rendering blocking code, still apply today. However, as more and more web apps are using JavaScript, it’s important to verify that our code is fast.
Suppose that you have a working function but you suspect it’s not as fast as it could be, and you have a plan to improve it. How do you prove this assumption? What’s the best practice for testing the performance of JavaScript functions today? Generally, the best way to achieve this task is to use the built-in performance.now() function and measure the time before and after your function executes.
In this article we’ll discuss h

Common File Permissions
Setting	Numerical	Meaning
-rw-------	(600)	Only the owner has read and write permissions.
-rw-r--r--	(644)	Only the owner has read and write permissions; the group and others have read only.
-rwx------	(700)	Only the owner has read, write, and execute permissions.
-rwxr-xr-x	(755)	The owner has read, write, and execute permissions; the group and others have only read and execute.
-rwx--x--x	(711)	The owner has read, write, and execute permissions; the group and others have only execute.
-rw-rw-rw-	(666)	Everyone can read and write to the file. (Be careful with these permissions.)
-rwxrwxrwx	(777)	Everyone can read, write, and execute. (Again, this permissions setting can be hazardous.)
