You can also now achieve this very simply by using an arrow function and the map() method of the Array:
var words = ['Foo','Bar','Fizz','Buzz'].map(v => v.toLowerCase()); console.log(words);
map() will only work in browsers which support ES2015. In other words, anything except IE8 and lower.
If you want to use lodash library you can do the following:
var words = ['Foo','Bar','Fizz','Buzz']
var result = map(words, (v) => lowerCase(v))
That’s it for now.
