typescript asking for template literal

Question

I'm using typescript, and is complaining when concatenating a string,

  const content = senderDisplay + ', '+ moment(timestamp).format('YY/MM/DD')+' at ' + moment(timestamp).format('h:mm A');

[tslint] Use a template literal instead of concatenating with a string literal. (prefer-template)

What is the template literal to fix this? cheers

Answer 1

You can see the template literals in MDN, and these are the prefered style in ES6.

In your case it would become the following:

const content = `${senderDisplay}, ${moment(timestamp).format('YY/MM/DD')} at ${moment(timestamp).format('h:mm A')}`;

Important differences:

• Starts and ends with a backtick

• Supports multiline strings

• Expressions are interpolated with ${expression}
