JavaScript does not support generic types or methods.
- source IListT
- A IListT to find an index in.
- predicate FuncT, Boolean
- A function to test each element for a condition.
- T
- Type of elements of source.
Int32Index of the first element in
source that matches the specified
predicate; otherwise,
-1.In Visual Basic and C#, you can call this method as an instance method on any object of type
IListT. When you use instance method syntax to call this method, omit the first parameter. For more information, see
