Answer 1

To make inline statement, quick is

var a=1; var b=2;
<div style={{column: a === b ? "if true style" : "else style"}}></div>
<div style={a === b ? {column: "if true style"} : {column: "if false style"}}></div>

or with only one statement:

<div style={{column: a === b && "value if true"}}></div>
