Check if a property exists using React.js

There are two options you can use. the && operator and If statement to check if the props exist. Option 1 will check if the property exists then run the second part of the code. It works like an if without the if.

Option 1

this.props.property && this.props.property

Option 2

if(this.props.property){
this.props.property
}

This also works with function names.

You can use this also check to render components and tags.
