1. Tuple definition
Store collections of elements of different types
2. Declare tuples
// 声明并初始化
var mytuple = [10, "Runoob"];
var mytuple1: [number, string] = [10, "Runoob"];
// 先声明后初始化
var mytuple = [];
mytuple[0] = 120
mytuple[1] = "ming"
3. Tuple operations
-
push()Add elements to the tuple, adding at the end
-
pop()Removes an element (the last one) from the tuple and returns the removed element
var mytuple = [];
mytuple[0] = 120;
mytuple[1] = "ming";
mytuple.push("hwm");
mytuple.forEach(element => {
console.log(element)
}); // 120, ming, hwm
console.log(mytuple.pop()); // hwm
