Although this class is not all encompassing by any means, it should assist assist you with any Javascript projects incorporating multi dimensional array use. Should you wish to add or extend the class, please feel free to do so. If you feel that others could benefit from your work, please include a message below and I will include your additions to the base class as appropriate.

init(): to initialize the class array
getLength(): to return the length of the array
getRowLength(row = [int]): to return the length of the array’s row
push(v = [mixed var]): push string or array of values onto the end of the array
rowPush(searchValue = [mixed var], addValues = [array]): Add array items to an existing row where the searchValue matches
