nado.editLength

nado.editLength support edit length of 2 Strings.

API

#levenshtein_distance(textA, textB) Levenshtein distance allows deletion, insertion, substition.

const ed = require('nado.editLength');
var strA = 'bluemoon';
var strB = 'mono';
var ld = ed.levenshtein_distance(strA, strB);

returned JSON

  edit_operation: {
    dispaly_A        : 'bluemoon',
    dispaly_operation: '----..XX',
    dispaly_B        : '    mono',
  } 
}

#damerau_levenshtein_distance(textA, textB) Demerau-Levenshtein distance allows deletion, insertion, substition and transposition.

const ed = require('nado.editLength');
var strA = 'bluemoon';
var strB = 'mono';
var ld = ed.demerau_levenshtein_distance(strA, strB);

returned JSON

  } 
}

#match_genome(test, target) find similar position between test sequence and target sequence.
