Can't understand one way binding in Angular2

For Binding Documents Angular2
[target]="expression"

create a one-way binding from the data source to view the targets. But when I do this target="HELLO WORLD"

it works great. Shouldn't the second command give me an error?

target="HELLO WORLD"

gives target

the string value HELLO WORLD

and [target]="expression"

gives target

the variable value expression

.



You can also do [target]="'HELLO WORLD'"

and it will be the same astarget="HELLO WORLD"
