What best practice when instantiating a JavaScript object? -


when instantiating object in javascript, (particularly when there multiple objects being instantiated in same script block) - practice wrap instantiation in try catch statement if object errors doesn't affect other objects within script?

e.g best practice this:

try{     new navigation(); }catch(e){   //handle exception navigation fail }  try{     new accordian(); }catch(e){   //handle exception accordion fail }

as opposed to

new navigation(); new accordian(); , on.....

i can't see reason doing that. if likelihood of error being thrown simple object instantiation high, there should wrong code. besides, try/catch statements known slow in javascript.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
