[Javascript] How to replace all spaces with `-` in a given string?

Question

I want to replace all the spaces with '-', for example., 'this is a test message' to 'this-is-a-test-message'. How can I do that in Javascript?

Use `replace()` method along with regex `/ /g` to replace all spaces. If you forget to include `g` it will replace only the first white space.

```js
let str = 'this is a test message';

console.log(str.replace(/ /, "-"));
console.log(str.replace(/ /g, "-"));
```
