OP strings (v0.3)

In op strings are arrays of bytes. Tipically, arrays stores texts encoded in a local encode format but in general strings can content binary data as images, sounds, ...

Creation

In op strings are created using quotes:

var s = "Native Big Data is the fastest Big Data platform ever created";s

Strings can be created form other objects:

var i = 12;
var number_12 = "" + i;number_12

Comparations

Comparation acts like other languajes. The following scripts will return true

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
var s_2 = "Native Big Data is the fastest Big Data platform ever " + "created";
s_1 == s_2

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
var s_2 = "Netive Big Data is the fastest Big Data platform ever " + "created";
s_1 < s_2

Searching and exploring data

The '[]' operator in strings is the best way to explore the data.

The length of a string can be obtained with the [] operator without parameters (or passing null) : The following scripts will return the length of the string:

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[]

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[null]

A byte from the string can be obtained with the [] operator with a number as parameter:

The following script will return the ascii code of the 'i' character:

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[3]

The '[]' operator with an array as a parameter acts as the 'substr' function in other languages:

The following script will return the substring between the 4 and 4+5 characters ('ve Bi') :

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ [ 4, 5 ] ]

The following script will return the substring between the length - 10 and length -10 + 5 characters (' ever') :

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ [ -10, 5 ] ]

The '[]' operator with a string as parameter acts as the 'indexOf' function in other languages:

This script will return 23

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ "faste" ]

Searching with an array will search beginning a point different of the beginning. This script will return 8

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ [ "i" ,4 ]   ]

With a 2nd parameter as false the searching will begin at the end. This script will return 31

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ [ "Big", false ]   ]

With a 2nd parameter as true the searching will return an array of all matches. This script will return [ 7, 31 ]

var s_1 = "Native Big Data is the fastest Big Data platform ever created";
s_1[ [ "Big", false ]   ]
