What is meant by hydroboration-oxidation reaction? Illustrate it with an example.

The addition of borane followed by oxidation is known as the hydroboration-oxidation reaction. In this reaction,an alkene reacts with diborane $(BH_3)_2$ to form a trialkylborane intermediate,which is then oxidized to an alcohol using hydrogen peroxide $(H_2O_2)$ in the presence of aqueous sodium hydroxide $(NaOH)$.
For example,the hydroboration-oxidation of propene yields propan$-1-$ol:
$CH_3-CH=CH_2 + (BH_3)_2 \to (CH_3-CH_2-CH_2)_3B$
$(CH_3-CH_2-CH_2)_3B \xrightarrow{3H_2O_2, OH^-} 3CH_3-CH_2-CH_2-OH + B(OH)_3$
The final product is propan$-1-$ol.
