To capitalize string in Javascript you can make use of the toUpperCase on the first letter then continue slicing through the string. To ease the process below is the "capitalize" that's attached to the "String prototype" in JavaScript.
/* add string capitalize helper */
Object.defineProperty(String.prototype, 'capitalize', {
value: function() {
return this.charAt(0).toUpperCase() + this.slice(1);
},
enumerable: false
});JavaScript Capitalize Helper Function
To make use of the code above you can now call the "capitalize()" function after defining the string.
"hello world".capitalize() // Hello world
