Equivalent of crossunder in ToS

[serendipity2020]

Whats the equivalent of below pine script in think script?

In pine, source1-series is defined as having crossed under source2-series if, on the current bar, the value of source1 is less than the value of source2, and on the previous bar, the value of source1 was greater than or equal to the value of source2

ta.crossunder(source1, source2)

Thanks in Advance
