JavaScript method for string translation and conversion through dictionary_javascript skills

The example in this article describes the method of JavaScript string translation and conversion through dictionary. Share it with everyone for your reference. The specific analysis is as follows:

Here is actually setting up a dictionary for comparison, and then using the translation function to find the corresponding key value from the dictionary. Requires JavaScript version 1.8 or above

The function is defined as follows:

function CreateTranslator(translationTable)
function(s) s.replace(
new RegExp([k for (k in translationTable)].join('|'), 'g'),
function(str) translationTable[str]
);

Calling method:

var translationTable = { a:1, bb:2, b:3, c:4 };
var MyTranslater = CreateTranslator( translationTable );
MyTranslater('aabbbc'); // returns: 11234

I hope this article will be helpful to everyone’s JavaScript programming design.
