Tests:

Split map
const result = text.split('').map(char => `_${char}`);
For loop
const result = []; for (let i = 0; i < text.length; i++) { const char = text[i]; result[i] = `_${char}` }
For loop optimized
const charCount = text.length; const result = new Array(charCount); for (let i = 0; i < charCount; i++) { result[i] = `_${text[i]}` }
