When I search for difference between let and var in javascript it says variable declared by let can't be redeclared but variables declared by var can be redeclared but does this line mean?
Well hello Vinay Singla the thing is when you use let you do not have to redeclare it.
Otherwise an error will pop and a new let is very similar when you declare variables in python .
Code you wrote will cause an error

Try this. You need to concatenate the variable with url
dt.ajax.url('test.php?status='+status).load();

I have the following code where MODE is a variable. Its value should be a method of jQuery's tinycolor liberary.
$cor = tinycolor($cor).mode(z).toString();
I'd like to call that method on that line so, for instance, when mode = 'lighten' $cor would be
$cor = tinycolor($cor).lighten(z).toString();
Is there a way of doing it this way?
Thanks!
Use bracket notation
$cor = tinycolor($cor)[mode](z).toString();

What is the difference between these two definitions? I can't make them clear.
There is no difference. But best practice is to avoid using new on JavaScript primitive types.
