CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory #7024

Hi i know already another post has been answer this problem before but, i just want to know what the differences between using
method 1 : node --max_old_space_size=8192 node_modules/\@angular/cli/bin/ng build --prod --aot
and using
method 2 : ng build --prod --aot false

if i using node --max_old_space_size=8192 node_modules/\@angular/cli/bin/ng build --prod --aot
the results always stuck on 92% like this

but if i using ng build --prod --aot false all process working well

i really not understand why just add false everything it works, but if i not using false the build will show error message CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

can you tell me what the problem in method 1?
