Create an empty object in JavaScript with {} or new Object()?
...sing new Object(); - whereas {}; can make your code more compact, and more readable.
For defining empty objects they're technically the same. The {} syntax is shorter, neater (less Java-ish), and allows you to instantly populate the object inline - like so:

title: 'Frog'...
Why can't C compilers rearrange struct members to eliminate alignment padding? [duplicate]
...lds. Reordering the fields would make it impossible for C code to directly read or write the header (assuming the ZIP implementation would like to access the data directly):
struct __attribute__((__packed__)) LocalFileHeader {
uint32_t signature;
uint16_t minVersion, flag, method, modTime, ...

lexers vs parsers
...
What parsers and lexers have in common:
They read symbols of some alphabet from their input.
Hint: The alphabet doesn't necessarily have to be of letters. But it
has to be of symbols which are atomic for the language
understood by parser/lexer.
Symbols for the lexer: ...
“where 1=1” statement [duplicate]
