Getting the largest number from an array
To find the largest value in an array of numbers, we can spread that array into Math.max() instead of manually iterating over it.
Read fire tipIf an array contains flat values, we can quickly turn those into objects by mapping over them. The name we give them in the call to Array.prototype.map()
becomes the name of the objects’ property when we do it like this.
// turn these strings into objects, where they become `name`-properties
['John', 'Paul', 'George', 'Ringo'].map(name => ({ name }))
// ⇒ [
// { name: 'John' },
// { name: 'Paul' },
// { name: 'George' },
// { name: 'Ringo' }
// ]
