The function only can solved with.map, i cant find the way to skip the first index of each string to solve the excercise.
`
let snakeToCamel = function(string) {
// Your code here
const result = string.split("_").map(char => char[0].toUpperCase() + char.toLowerCase());
return result.join("");
};
console.log(snakeToCamel('snakes_go_hiss')); // 'SnakesGoHiss'
console.log(snakeToCamel('say_hello_world')); // 'SayHelloWorld'
`
This is my best trie, i google for answers but i dont find nothing with.map method, if anyone know where are my error i been so grateful. Thanks!
PD: I can't use.replace!
I SOLVED, REPLACING THE "... + char.toLowerCase()" to "char.substring(1).toLowerCase()"
Rather than index specifiers []
, I would use slice for this..
char.slice(0,1)
get first char, char.slice(1)
, get chars from index 1 to end..
eg.
let snakeToCamel = function(string) { const result = string.split("_").map(char => char.slice(0,1).toUpperCase() + char.slice(1).toLowerCase()); return result.join(""); }; console.log(snakeToCamel('snakes_go_hiss')); // 'SnakesGoHiss' console.log(snakeToCamel('say_hello_world')); // 'SayHelloWorld'
