如何将传递的字符串转换为骆驼案例

Question

Hi I'm working on a problem that requires me to 'returns the passed string convertedToCamelCase'

I tried doing it like this

let wordsArr = words.toLowerCase().split(" ")
  for (let i = 1; i<wordsArr.length; i++){
  wordsArr[i] = wordsArr[i].charAt(0).toUpperCase()
  wordsArr.slice(1)
  }
  return wordsArr.join("")

but that doesnt seem to work and now im stuck

Answer 1

Something like this should work if it doesn't contain punctuation

 let camelot = "I have to push the pram a lot"; const makeCamel = s => { let camelArray = s.toLowerCase().split(' ') let newArray = [camelArray[0]] for (let i in camelArray) { if (i >= 1) { let capLetter = camelArray[i][0].toUpperCase() let rest = camelArray[i].slice(1); let newWord = capLetter + rest newArray.push(newWord); } } return newArray.join(''); } makeCamel(camelot)

Try indexing from 0 instead of 1 in your initializing loop
