# Truncate the text
|
|
|
|
Create a function `truncate(str, maxlength)` that checks the length of the `str` and, if it exceeds `maxlength` -- replaces the end of `str` with the ellipsis character `"…"`, to make its length equal to `maxlength`.
|
|
|
|
The result of the function should be the truncated (if needed) string.
|
|
|
|
For instance:
|
|
|
|
```js
|
|
truncate("What I'd like to tell on this topic is:", 20) = "What I'd like to te…"
|
|
|
|
truncate("Hi everyone!", 20) = "Hi everyone!"
|
|
```
