TypeScript - Angular: Multiline string

Wrap the text in ` (backticks) instead of single quotes ', then it can span multiple lines.

var myString = `abc
def
ghi`;

the accepted answer works only if we want \n added in our string , if we just want content to be on newline without adding \n in the long string , please add \ at the end of every line like this

string firstName = `this is line 1 \
and this is line 2 => yet "new line" are not \
included because they were escaped with a "\"`;

console.assert(firstName == 'this is line 1 and this is line 2 => yet "new line" are not included because they were escaped with a "\"'); // true

Note - make sure you are not adding any tabs and spaces in the beginning of the next(second in the example) line
