Javascript micro-optimizations
NOTE: This document is OLD - and most of the tips here are probably outdated, since newer versions of Javascript have been
released over the years - with newer optimizations and more emphasis on optimizing newly supported syntax.
// Array literal (= []) is faster than Array constructor (new Array())

var array = [];

MySQL to Sqlite converter
#!/bin/sh
# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
