what is JavaScript and what is js engine |

[@devT44]

What's difference between compiler and jit compiler? Why js engine uses jit compiler instead of normal compiler?

a regular compiler translates the entire program upfront, a JIT compiler translates parts of the code just before they're needed, which can lead to better performance, especially for dynamic languages like JavaScript used in web development.
