Exercise Goal
Switch based on the film's episode number (1-6) to output an emoji showing how you feel about the film.
Tasks
- Open the app.component.html template file.
- One line 5 (after the title) create a new
<div>
element. Apply theNgSwitch
attribute directive to this element, and switch on thefilm.episode
value. - Within the newly created
<div>
element, create six new<span>
elements for each episode. - On each
<span>
element use theNgSwitchCase
structural directive to specify the episode number, from1
to6
. - Within each span either use a thumbs-up or a thumbs-down emoji to indicate if you liked the episode. You can also simply use the text "YASSS" or "meh..." within each
<span>
according to your tastes.
Exercise
Notes
- Keep in mind that we're using both the
NgSwitch
attribute directive along with theNgSwitchCase
structural directive in this exercise. - The
NgSwitch
attribute directive accepts the value that you are "switching" on. This is similar to the expression that is specified in theswitch ()
statement in JavaScript. - The
NgSwitchCase
structural directive accepts an expression upon which we will evaluate against the value specified to theNgSwitch
directive. - In this exercise, we are "switching" on the
film.episode
property, and we are conditionally rendering a<span>
element based on the value of the episode, the integers1
through6
.
