I read an [article](https://freedom-to-tinker.com/2013/10/09/the-linux-backdoor-attempt-of-2003/) recently that described an attempted back door in the Linux kernel and it got me thinking about language safety.

First I tested beloved Rust:

`cargo run`
```
error[E0308]: mismatched types
 --> src/main.rs:3:8
  |
3 |     if ligma = 4 {
  |        ^^^^^^^^^ expected `bool`, found `()`
  |
help: you might have meant to compare for equality
  |
3 |     if ligma == 4 {
  |               +

For more information about this error, try `rustc --explain E0308`.
error: could not compile `linux_03_backdoor_test` (bin "linux_03_backdoor_test") due to 1 previous error
```
of course it threw a fit.


Next up is Python:

`python test.py`
```
  File ".../test.py", line 3
    if ligma = 4:
       ^^^^^^^^^
SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '='?
```
Python caught it.


Next, JavaScript:
WHY!??

`node test.js`
```
4
```
This is why I hate JS.
