// Usage examples:6
7
console.log(decapitalizeTest('Abc')); // abc8
console.log(decapitalizeTest('John said: This is text')); // john said: This is textES6:
xxxxxxxxxx1
const decapitalizeTest = (text) => {2
return text && text[0].toLowerCase() + text.slice(1) || text;3
};4

// Usage examples:6
7
console.log(decapitalizeTest('Abc')); // abc8
console.log(decapitalizeTest('John said: This is text')); // john said: This is textNaive solution:

console.log('Abc'.toLowerCase()); // abc2
console.log('John said: this is text'.toLowerCase()); // john said: this is textNote: in above naive solution we believe that
