不知不觉这么多年了，从java到现在,也学了不少了,也感谢当初决定毅然走向php,放弃java栈到现在...

偶尔回味下,偶尔有人问我精通哪门?精通如何谈,语言特性不断在更新..

合适的项目和业务场景,选型正确的语言有利于提高效率，降低重复造船过程...

作为一名程序员,时刻记住fight~!不断提升自己~!

总结一下语法:

  1.字符串:

#java
String name = "Bill";

#php
$name = "Bill";

#javascript
var name = "Bill";
let name = "Bill";

#python
name = "Bill"

#golang
name := "Bill"

2.数：

#java
int num = 64;
double dnum = 64.001;
float fnum = 64.02f;

#php
$num = 64.00;

#javascript
var name =64.00;
let name = 64.00;

#python
num = 64.00

#golang
var num float32 = 1.00 //强调类型方式
num := 64.00 //弱类型方式

3.List:

#java
int[] num = {0,1,2,3,4};
int[] num = new int[10];

#php
$intArray = [];

#javascript
var numArray = [];

#python
numlist = []

#golang
num := []int{1, 2, 3, 4, 5}

4.MAP:

#java 
Map<String, Integer > map1 = new HashMap<String, Integer >();
map1.put("Bill", 1);

#php
$map = ["1" => "Bill"];

#javascript
var map = {};
map["1"] = "Bill";

#python
map = {}
map["name"] = "Bill"

#golang
people := map[string]string{}
people["name"] = "Bill"

主要用以上几种,关于线程安全类型的不做介绍了。

凭记忆写的，如果有错误请留言.

Ps:golang有时定义建议确定长度和类型命名对存储结构有溢
