What are the basic data types in es6
The basic data types in es6 include six types: "Number", "String", "Boolean", "Symbol", "null" and "undefined": 1., including integers and floating point numbers, used for Represents a numerical value; 2. String, used to represent text data; 3. Boolean, represents logical true or false; 4. Symbol, used as a unique identifier for object attributes; 5. null, represents a null value or non-existence Object; 6. undefined.
# Operating system for this tutorial: Windows 10 system, Dell G3 computer.
In ES6 (ECMAScript 2015), the basic data types have not changed from previous versions, and still include the following types:
Number (Number): including integers and floating point numbers, used to represent numerical values, such as: 42, 3.14.
String: used to represent text data, such as: "Hello, World!".
Boolean value (Boolean): represents logical truth or falsehood, that is, true or false.
Symbol: A new data type in ES6 that represents a unique value and is used as a unique identifier for object attributes.
In addition, a new basic data type was introduced in ES6:
- Null value (null): represents a null value or does not exist object.
In addition, there is a special basic data type:
- Undefined (undefined): represents an uninitialized variable value.
These basic data types are still the most basic and commonly used data types in JavaScript in ES6. They are used to store and process various data and are the basic building blocks of the JavaScript language.

Is async for es6 or es7?
Jan 29, 2023 pm 05:36 PM
async is es7. async and await are new additions to ES7 and are solutions for asynchronous operations; async/await can be said to be syntactic sugar for co modules and generator functions, solving js asynchronous code with clearer semantics. As the name suggests, async means "asynchronous". Async is used to declare that a function is asynchronous; there is a strict rule between async and await. Both cannot be separated from each other, and await can only be written in async functions.
How to find different items in two arrays in es6
Nov 01, 2022 pm 06:07 PM
Steps: 1. Convert the two arrays to set types respectively, with the syntax "newA=new Set(a);newB=new Set(b);"; 2. Use has() and filter() to find the difference set, with the syntax " new Set([...newA].filter(x =>!newB.has(x)))", the difference set elements will be included in a set collection and returned; 3. Use Array.from to convert the set into an array Type, syntax "Array.from(collection)".
Why does the mini program need to convert es6 to es5?
Nov 21, 2022 pm 06:15 PM
For browser compatibility. As a new specification for JS, ES6 adds a lot of new syntax and API. However, modern browsers do not have high support for the new features of ES6, so ES6 code needs to be converted to ES5 code. In the WeChat web developer tools, babel is used by default to convert the developer's ES6 syntax code into ES5 code that is well supported by all three terminals, helping developers solve development problems caused by different environments; only in the project Just configure and check the "ES6 to ES5" option.
How to implement array deduplication in es5 and es6
Jan 16, 2023 pm 05:09 PM
In es5, you can use the for statement and indexOf() function to achieve array deduplication. The syntax "for(i=0;i<array length;i++){a=newArr.indexOf(arr[i]);if(a== -1){...}}". In es6, you can use the spread operator, Array.from() and Set to remove duplication; you need to first convert the array into a Set object to remove duplication, and then use the spread operator or the Array.from() function to convert the Set object back to an array. Just group.
What are the characteristics of basic data types?
Nov 10, 2023 pm 01:52 PM
Basic data types have the characteristics of fixed size, fixed value range, immutability, direct access to memory, default value, operation rules, occupied storage space, speed, special functions and conversions. Detailed introduction: 1. Fixed size. Basic data types have a fixed size when declared, which means that the storage space of each basic data type is the same under any circumstances and will not change due to the value of the variable; 2. Fixed value range, each basic data type has a fixed value range; 3. Immutability, basic data types are immutable, etc.
What does es6 temporary Zenless Zone Zero mean?
Jan 03, 2023 pm 03:56 PM
In es6, the temporary dead zone is a syntax error, which refers to the let and const commands that make the block form a closed scope. Within a code block, before a variable is declared using the let/const command, the variable is unavailable and belongs to the variable's "dead zone" before the variable is declared; this is syntactically called a "temporary dead zone". ES6 stipulates that variable promotion does not occur in temporary dead zones and let and const statements, mainly to reduce runtime errors and prevent the variable from being used before it is declared, resulting in unexpected behavior.
What are the basic data types of plc
Nov 02, 2023 am 10:40 AM
The basic data types of plc include bits, bytes, integers, floating point numbers, strings, Boolean, time, counters, timers, etc. Detailed introduction: 1. Bit: represents a switch state, which can be 0 or 1; 2. Byte: represents 8-bit data, which can store integer values (0-255) or characters; 3. Integer (Integer): represents a signed integer value, which can be a positive number, a negative number, or zero; 4. Float (Float): represents a real value with a decimal part, which can be single precision (32 bits) or double precision (64 bits) )wait
Is es6 map ordered?
Nov 03, 2022 pm 07:05 PM
The map is ordered. The map type in ES6 is an ordered list that stores many key-value pairs. The key names and corresponding values support all data types; the equivalence of key names is determined by calling the "Objext.is()" method. Implemented, so the number 5 and the string "5" will be judged as two types, and can appear in the program as two independent keys.
