Convert dash-separated string to camelCase?

Question

For example suppose I always have a string that is delimited by \"-\". Is there a way to transform

it-is-a-great-day-today

to

itIsAGreatDayToday

Answer 1

'it-is-a-great-day-today'.split('-').map(function(x,i){
    return (i?x[0].toUpperCase():x[0]) + x.slice(1).toLowerCase()
}).join('')

Result:

'itIsAGreatDayToday'

Alternatively, .match(/\w+/g) rather than .split('-') -- depending on what you want to do in edge cases like "this--is-a-test".
