How to express this in regex?

Question

must be true ``` kword_search = "void main(){" kword_search = " void main(){" kword_search = "void main (){" kword_search = " void main ( ){" ``` what i've done so far: ``` /\s*void\s+main\s*(\s*)$/.test(kword_search) ``` The problem here kword_search = "void main" returns true with the condition i wrote. I want to do get inside a condition when the looping char is in the '{' position

Accepted Answer

You must escape the parenthesis :

```
/\s*void\s+main\s*$\s*$$/.test(kword_search)
```

But with the $ at the end, it won't accept the {, so you probably want

```
/\s*void\s+main\s*$\s*$\s*{$/.test(kword_search)
```
