Arent buggy? React had to introduce a compiler because the masses only write buggy code. The reason they likely waited so long to do it is because they felt like it was a waste to write software to fix something that theoretically has “no flaws” because it’s “just JavaScript”.

Literally every other JS framework figured this out years and years ago and some over a decade ago. Compilers help to raise the floor for everyone so we don’t need to worry about making a dumb mistake and drastically slowing down our programs. Compilers are the evolution of software.
