The best thing to do in order to use quotes within a string in JavaScript is to use backticks (` `) instead of single or double quotes. Let’s see this with an example:

let secondString = "this is "green"";

let thirdString = `this is 'blue'`;


console.log(secondString);
// this returns an error

console.log(thirdString);
//  returns -- this is 'blue'

Another way is to use the backward slash (\) in the following way:

let secondString = "this is \"green\"";

console.log(secondString);
// returns -- this is "green"
