I'm getting an unexpected token error in my ternary code expression. The error message points to the first = in the ===. What am I getting wrong here?

```
const getMyHeader = (heading, advisorTags) => {
    if (advisorTags.length > 0) {
      return (
        <Typography
          variant="h6"
          component="h6"
          style={{
            heading === 'White Advantages'
              ? 'fontSize: 16'
              : 'fontSize: 16, paddingTop: 10'
          }}
        >
          {heading}
        </Typography>
      );
    } else {
      return '';
    }
  };

```
