joinClasses

Joins all given classes strings to one html-class-attribute String. Individual Strings that are null or blank are filtered out.

Examples

val classes = joinClasses(
    "class1",
    null,
    "class2",
    ""
)
println(classes) // prints "class1 class2"

Using this function, it is also possible to conditionally construct classes strings without having to do dangerous string concatenation:

val classes = joinClasses(
   "class1",
   "class2".takeIf { it.length 10 }
)

println(classes) // prints "class1"
