Description

Description:

Searches for an element within array for which the code evaluates to true. Returns the 0 based index on success or -1 if not found. Code on the right side of the command is evaluated for each element of the array, processed element can be referenced in code as _x.

NOTE: Because command findIf terminates as soon as it finds an element that fulfills the condition, it is more efficient then count in scenarios where you need to check for presence / absence of at least one element that evaluates to true.

Example 1:
