Javascript - Shorthand for Switch statement

You might have seen similar code in javascript. I wanted to understand how it is working. As it does not look like a ternary expression.

return {
  "false": React.DOM.a({
    href: "javascript:void(0)",
    onClick: this.linkClicked
  }, "Click Me Now"),
  "true": React.DOM.span({}, "You have clicked")
}[this.state.clicked];

While discussing with team we found that, it is nothing, but a SWITCH CASE

So when we execute above mentioned code, if "this.state.clicked" is TRUE then it will show SPAN with text 'You have clicked'". This is just a shorthand for SWITCH, so we do not have to write complete "SWITCH CASE" statement.

You can try this code in your console and see it working.

clickState = 'true';
alert({
      "false": "I am FALSE case",
      "true": "I am TRUE case"
    }[clickState]
)
