JavaScript: Writing Precise Code for Clear Results

JavaScript: "4" + "3" → 43 This isn’t a bug. It’s a reminder. Computers don’t understand intent. They understand instructions. Most production bugs don’t come from bad languages — they come from unclear assumptions. Write precise code. Think like the machine. That’s where real engineering begins.

Appreciate you mentioning us. 💚

Big thanks for the shoutout! We're grateful for your support! 💖

Ok, you wanna do this? Explain to me now why "4" - "3" gives "1" then?

Before university: 4+3 = 43 is obviusly a error After university: 4+3 = 43 is perfectly valid, it depends on how you define "+". + is just another symbol that you can give any meaning 4+3=43 is a bunch of symbols that you can define what are the meaning, not a single meaning is "correct". You could write 4 3 + and it will be has valid 4+3

Well, isn't AI meant to deal with implementation details for machines and let people think in terms of human's needs? I was looking into some Vitis HLS code which was running without any problems in csim, but miserably failing cosim. A bot looked into into a gazillion of very cryptic autogenerated Verilog files and after some iterations said, Aha! This FSM_628 is missing alignment on ap_872 in comparison with d_247 because the struct blah is automatically and incorrectly padded by Vitis, let's define the padding as reserved field. Boom, it worked.... How much time a human biological brain would spend thinking like a machine on this?

Learning the idiosyncrasies of a programming language is not engineering. Engineering is the application of scientific principles to solve problems.

Using strings for math is like trying to eat soup with a knife. Technically you have a tool (data type) but it is the wrong one for the job. The real lesson is not about JavaScript. It is about knowing the limits and understanding the tool you are using.

Yeah , it takes instructions literally as they are given hahaha 💯

I assume everything as string ,unless told

I thought bro added up two strings already from the image
