What does ${} (dollar sign and curly braces) mean in a string in Javascript?
You're talking about template literals.
They allow for both multiline strings and string interpolation.
Multiline strings:
console.log(`foobar`);// foo// barString interpolation:
var foo = 'bar';console.log(`Let's meet at the ${foo}`);// Let's meet at the bar
As mentioned in a comment above, you can have expressions within the template strings/literals. Example:
const one = 1;const two = 2;const result = `One add two is ${one + two}`;console.log(result); // output: One add two is 3
You can also perform Implicit Type Conversions with template literals.Example:
let fruits = ["mango","orange","pineapple","papaya"];console.log(`My favourite fruits are ${fruits}`);// My favourite fruits are mango,orange,pineapple,papaya
