+### spread
+
+Implements javascript's spread syntax as a function. Flattens the list(non-deep) and returns an array.
+
+```python 
+def spread(arg):
+    ret = []
+    for i in arg:
+        if isinstance(i, list):
+            ret.extend(i)
+        else:
+            ret.append(i)
+    return ret
+
+```
+
+
+```python
+spread([1,2,3,[4,5,6],[7],8,9]) # [1,2,3,4,5,6,7,8,9]
+```
