Coding Dojo, a tech training provider, has revealed the top ten development languages that employers are looking for in job candidates.

Coding Dojo will hold more than 30 free workshops this year at its six campuses, from Seattle to Washington D.C., to help Amazon spread the word on how to write code for Alexa.

Coding Dojo was founded in 2012, and moved its headquarters to Bellevue in 2015. It also has locations in Silicon Valley, Los Angeles, and Dallas.
