+### ForEachWhile
+
+Iterates over collection elements and invokes iteratee for each element collection return value decide to continue or break, like do while().
+
+```go
+list := []int64{1, 2, -42, 4}
+
+ForEachWhile(list, func(x int64, _ int) bool {
+    if x < 0 {
+        return false
+    }
+    fmt.Println(x)
+    return true
+})
+
+// 1
+// 2
+```
+
 ### Times
 
 Times invokes the iteratee n times, returning an array of the results of each invocation. The iteratee is invoked with index as argument.
