Reality is a bit more nuanced that that. Some languages are easier to interpret and optimize than others, leading to less error-prone interpreter/compiler code. JS is definitely on the “harder to optimize” side of the spectrum, leading to very complex code with a higher chance of subtle errors.
V8 does some crazy stuff that makes JS one of the fastest interpreted language there is. But had JS been designed differently (Dart was an attempt at fixing some of those mistakes), it’s likely there would be less security vulnerabilities in its interpreter.
