Typescript: Array.from

var str1 = Array.from("sangram")

console.log(str1)

var set = new Set()

set.add("sagar").add("sangram").add("sachin")

console.log(set)

var myarr1 = Array.from(set)

console.log(myarr1)

var double = Array.from([1, 2, 3], (x) => x + x)

console.log(double)

var indexArray = Array.from({ length: 5 }, (_current, index) => {

return index

})

//_current here underscore say we dont need this variable in function

console.log(indexArray)

Output:

[ 's', 'a', 'n', 'g', 'r', 'a', 'm' ] Set(3) { 'sagar', 'sangram', 'sachin' } [ 'sagar', 'sangram', 'sachin' ] [ 2, 4, 6 ] [ 0, 1, 2, 3, 4 ]
