Change string based on a condition - JavaScript
We are required to write a JavaScript function that takes in a string. The task of our function is to change the string according to the following condition −
- If the first letter in the string is a capital letter then we should change the full string to capital letters.
- Otherwise, we should change the full string to small letters.
Example
Following is the code −
const str1 = "This is a normal string";
const str2 = "thisIsACamelCasedString";
const changeStringCase = str => {
let newStr = '';
const isUpperCase = str[0].charCodeAt(0) >= 65 && str[0].charCodeAt(0) <= 90;
if(isUpperCase){
newStr = str.toUpperCase();
}else{
newStr = str.toLowerCase();
};
return newStr;
};
console.log(changeStringCase(str1));
console.log(changeStringCase(str2));Output
Following is the output in the console −
THIS IS A NORMAL STRING thisisacamelcasedstring
