Join Justin Schwartzenberger for an in-depth discussion in this video Property binding, part of Angular 2 Essential Training.
- [Instructor] Another way you combine data in templates…with Angular is through property binding.…HTML elements have backing dom properties…that track state on elements.…You can use Angular's property binding syntax…to wire into those properties.…You do this with a specific syntax,…a pair of square brackets around a property name…on an element, and you set these…equal to a template expression following the same rules…as you do for interpolation.…
So, in the media-item.component.html file…let's add a text content property to the h tag…which is a native dom property for tracking…text content in an element.…Then we surround it with square brackets…and set it equal to the name expression context property.…Now we can remove the interpolation statement…from within the h tag.…
And when we switch over to the browser…we see we have the same result.…Using the property binding syntax…of the square brackets, tells Angular that you want it…to evaluate an expression for that property.…If we leave off the brackets,…and we switch back over to the reloaded browser,…
