Program to Convert String from Snake_Case to CamelCase in JavaScript

Snake_Case: A string in snake_case uses the underscore character to separate each word. Each word in a snake_case string usually begins with a lowercase letter, although variants exist.

CamelCase: A camelCase string begins with a lowercase letter, each following word beginning with an uppercase letter. There are no intervening spaces or punctuation in a camelCase string.

Code:

let snakeCaseString = "The_Tech_Platform"
 const snakeToCamelCase = sentence => sentence
  .split('_')
  .map((word, index) => {
  if (word === 0) {
  return part.toLowerCase();
  }
  return firstUppercase(word);
  })
  .join('');
 const firstUppercase = word => word &&
  word.charAt(0).toUpperCase() + word.slice(1);
 
 console.log(snakeCaseString);
 console.log(snakeToCamelCase(snakeCaseString));

Output:
