jquery - When adding JavaScript data to a page what's more efficient: creating new elements or populating existing ones? -


i have page i'm adding api response data creating new html elements data.

should creating html elements on page , them via script populate them?

is less efficient create them in js or not matter?

thanks

changing contents of element, or appending element?

both cases requires redraw in cases, right answer efficient solution if need change many elements, create elements in documentfragment, , append them dom in 1 go, instead of changing contents of many elements existing in dom, requiring redraw each manipulation.

as sidenote, cloning elements faster creating new ones.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
