How do I add a separator between elements in an {{#each}} loop except after the last element?
I know I'm late to the parts but I found a WAYYYY simpler method
{{#unless @last}},{{/unless}}
Since Ember v1.11 you are able to get the index of an each using block parameters. In your case this would look something like this:
{{#each list as |item index|}} {{if index ", "}}{{item.name}} {{item.status}}{{/each}}The first index value will be 0 which will evaluate to false and will not be added, all subsequent values will evaluate to true which will prepend a separator.
You can use standard CSS to do this:
li:after { content: ',';}li:last-of-type:after { content: '';}I prefer separate rules, but a more concise if slightly less readable version (from @Jay in the comments):
li:not(:last-of-type):after { content: ',';}
