Writing an İf condition at React

I try to write an if statement inside the loop but it gives an error. I tried to use {} but it does not work too, how can I write it properly.

`<Option
      optionText={option}      

 colorText = {props.colors[index]}
      priceText = {props.prices[index]}
      rangeText = {props.ranges[index]}
      domainText = {props.domains[index]}

    if(this.props.colorText == this.props.domainText){
      //I want to write a if condition here but it says Identifier expected
    }
      count= {index + 1}
      handleDeleteOption={props.handleDeleteOption}
    />
    </div> 
      )) 
    }  
  </div>`
