Check If Statement when you are dynamically creating something?

I am dynamically creating rows in my table using JavaScript. I need to add If statement inside a <td> which I am creating dynamically. Inside my <td> I have an anchor tag <a>. I need to add anchor tag only if it satisfies my If statement. Following is my code:

var IsAdmin = true;
var row;
row = "<tr><td>" + if(IsAdmin == true){ + "<a href='#'> </a>" + } + "</td></tr>"

I am getting following error in my console:

Uncaught Syntax Error: Unexpected token if

What am I doing wrong?
