Rule Details
This rule enforces spacing around the *
in yield*
expressions.
Options
The rule takes one option, an object, which has two keys before
and after
having boolean values true
or false
.
-
before
enforces spacing between theyield
and the*
. Iftrue
, a space is required, otherwise spaces are disallowed. -
after
enforces spacing between the*
and the argument. If it istrue
, a space is required, otherwise spaces are disallowed.
The default is {"before": false, "after": true}
.
"yield-star-spacing": ["error", {"before": true, "after": false}]
The option also has a string shorthand:
{"before": false, "after": true}
→"after"
{"before": true, "after": false}
→"before"
{"before": true, "after": true}
→"both"
{"before": false, "after": false}
→"neither"
"yield-star-spacing": ["error", "after"]
