JavaScript - Single Line IF ELSE

properties['Value'] = (IsItMuted === true) ? 'On' : 'Off';  

The ? : is called a ternary operator and acts just like an if/else when used in an expression

var testValue= (props.brtUser === 'No') ? 'Promote to User' : 'Demote to Contact';

Use this <p>{testValue}</p>
