Javascript Programmer Quotes

The programmer who refuses to keep exploring will surely stagnate, forget his joy, lose the will to program (and become a manager).

The most beautiful programming language in the world is useless unless it allows you to write the program that you need.

The difference between a bad programmer and a good programmer is understanding. That is, bad programmers don’t understand what they are doing and good programmers do. —Max Kanat-Alexander

The computer programmer is a creator of universes for which he alone is responsible. Universes of virtually unlimited complexity can be created in the form of computer programs. — Joseph Weizenbaum, Computer Power and Human Reason

For the Chrome project, we created a sub-OKR to turbocharge JavaScript. The goal was to make applications on the web work as smoothly as downloads on a desktop. We set a moonshot goal of 10x improvement and named the project “V8,” after the high-performance car engine. We were fortunate to find a Danish programmer named Lars Bak, who’d built virtual machines for Sun Microsystems and held more than a dozen patents. Lars is one of the great artists in his field. He came to us and said, without an ounce of bravado, “I can do something that is much, much faster.” Within four months, he had JavaScript running ten times as fast as it ran on Firefox. Within two years, it was more than twenty times faster—incredible progress. (Sometimes a stretch goal is not as wildly aspirational as it may seem. As Lars later told Steven Levy in In the Plex, “We sort of underestimated what we could do.”)

Errors in code are what programmers call bugs, though when our programs go wrong, we prefer to call them “unexpected additional features.” Very

The only thing worse than not knowing why some code breaks is not knowing why it worked in the first place! It's the classic "house of cards" mentality: "it works, but I'm not sure why, so nobody touch it!" You may have heard, "Hell is other people" (Sartre), and the programmer meme twist, "Hell is other people's code." I believe truly: "Hell is not understanding my own code.

The main purpose of a script written in a scripting language such as JavaScript, or VBA (Visual Basic for Applications) is to control another application. So you can say that, in some ways JavaScript controls the web browser, and VBA controls a Microsoft® Office application such as MS Word or MS Excel.

In JavaScript, most I/ O operations are provided through asynchronous, or nonblocking APIs. Instead of blocking a thread on a result, the programmer provides a callback (see Item 19) for the system to invoke once the input arrives:

Few classical programmers found prototypal inheritance to be acceptable, and classically inspired syntax obscures the language’s true prototypal nature. It is the worst of both worlds.
