corresponding values from a named list.
Usage
replace_placeholders(template_string, values_list)
Arguments
- template_string
A character string containing placeholders.
- values_list
A named list where names correspond to placeholders in the
template string (without the curly braces).

placeholder is not found in `values_list` or its value is `NULL`,
it's replaced with an empty string.

list(name = "Alice", day = "Monday"))
#> [1] "Hello, Alice! Today is Monday."
replace_placeholders("Topic: {{topic}}, Question: {{question}}",
list(topic = "AI Ethics")) # {{question}} becomes ""
#> [1] "Topic: AI Ethics, Question: "
