⟩ How to manage exception handling in Javascript?

► Javascript provides the features of exception handling using try..catch..finally blocks which is much similar to the C# exception handling blocks.

► We have to write the suspected code in try block and all the exceptions that occur in the try block will be caught in catch block.

► For example :

window.onload = function()

{

try

{

var v1=30;

var v2 =v1/v3;

}

catch(ex)

{

document.write(ex.name + " : " +ex.message);

}

Finally

{

document.write('this is finally block');

}

}

► This code snippet will cause an error :

TypeError : 'v3' is undefined.
