I am trying to iterate over some values of an Object using .map(). I need to escape a value. My code is like below

let modalrows = Object.keys(this.props.element).map((item,index) => ( if(item !== 'id') { //I am getting error in this line <tr key={index}> <td className="ui header data_type"> {item === 'name'? 'Name':null} </td> <td>{this.props.element[item]} <span>Edit</span></td> </tr> } ));

You need a bracets to start a code block. Right now you try to use if in a return expression. Fixed with braces:

let modalrows = Object.keys(this.props.element).map((item, index) => { if (item !== "id") { return ( <tr key={index}> <td className="ui header data_type"> {item === "name" ? "Name" : null} </td> <td> {this.props.element[item]} <span>Edit</span> </td> </tr> ); } });

Alternatively, you could use filter to first filter out unnecessary elements:

let modalrows = Object.keys(this.props.element) .filter(item => item !== "id") .map((item, index) => ( <tr key={index}> <td className="ui header data_type">{item === "name" ? "Name" : null}</td> <td> {this.props.element[item]} <span>Edit</span> </td> </tr> ));
