To create a multiline strings, the most common way is to concatenate them as shown below:
const multilineStrings = 'This is a\n' + 'multiline\n' + 'strings';Joining an array of strings is another approach:
const multilineStrings = ['This is a', 'multiline', 'strings'].join('\n');ES6 introduces an easier way to do that. It uses the template literal which is delimited by backticks:
const multilineStrings = `This is a
multiline
strings`;
