`str_c()` is very similar to the base `paste0()`, but is designed to be used with `mutate()` by obeying the usual tidyverse rules for recycling and propagating missing values:
```{r}
df <- tibble(name = c("Flora", "David", "Terra"))
df <- tibble(name = c("Flora", "David", "Terra", NA))
df |> mutate(greeting = str_c("Hi ", name, "!"))
```
