angular - Multiline string with typescript - Angular2 -

i'm angular2 beginner , i've written piece of code in dev/app.component.ts

it works, when go browser "max brown displayed". want write template part on different lines this:

but error in chrome console:

uncaught typeerror: cannot read property 'split' of undefined 

wrap text in ` (backticks) instead of single quotes ', can span multiple lines.

var mystring = `abc def ghi`;
