To capitalize the first letter<\/strong> of a string in JavaScript, you can use this simple function:<\/em><\/span><\/h3>\n
\n
function<\/span> capitalizeFirstLetter<\/span>(str<\/span>) {
\nif<\/span><\/code><\/div>\n
(!str) return<\/span> ''<\/span>;<\/code><\/div>\n
return<\/span> str.charAt<\/span>(0<\/span>).toUpperCase<\/span>() + str.slice<\/span>(1<\/span>);<\/code><\/div>\n
}
\n<\/code><\/div>\n<\/div>\n

\u2705 Example:<\/span><\/h3>\n
\n
console<\/span>.log<\/span>(capitalizeFirstLetter<\/span>(\"hello\"<\/span>)); \/\/ Output: \"Hello\"<\/span>
\nconsole<\/span>.log<\/span>(capitalizeFirstLetter<\/span>(\"javaScript\"<\/span>)); \/\/ Output: \"JavaScript\"<\/span>
\n<\/code><\/div>\n<\/div>\n
