Method call and property is not converted properly

[OzelotVanilla]

Description
The method/property in JavaScript is different from SCLang. However, it is currently converted directly.

Reason for Warning
Should be converted in order SCLang could process on.

Proposed Solution (if exists)
Make polyfills class for JavaScript class, such as Object, Array, or Map.

Currently working on the Array, try to be as fast as possible. Code example:

TSTOSC__Array
{
    var storing_array ;
    normIndex { |i| if( i >= 0, { ^i }, { ^this.length + i } ) ; }

    // other definitions...

    concat { |...array_or_values| ^TSTOSC__Array.new(storing_array ++ array_or_values.insert(0, []).reduce(_ ++ _)) ; }

    entries { ^TSTOSC__Array.new(storing_array.collect({ |item, index| TSTOSC__Array.new([index, item]) ; })) ; }

    find { |checker| ^storing_array.detect({ |item, index| checker.(item, index, this) ; }) ; }

    findLast
    { |checker|
        var i = this.length - 1 ;
        while ({ i >= 0}, { if(checker.(this[i], i, this), { ^this[i] }, {}) ; i = i - 1 ; }) ;
        ^nil ;
    }

    flat { |depth=1| ^TSTOSC__Array.new(storing_array.flatten(depth)) ; }

    map { |mapper| ^TSTOSC__Array.new(storing_array.collect({ |item, index| mapper.(item, index, this) ; })) ; }
}
