This article mainly explains "es6 how to judge whether two strings are equal". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "es6 how to judge whether two strings are equal".

Judgment method: 1, using the "= =" operator, you can compare whether the values on both sides of the equation are equal, the syntax "string 1 = = string 2"; 2, with "Object.is ()", the syntax "Object.is (string 1, string 2)", if the two strings are of the same length and the same characters are arranged in the same order, then the two strings are equal.

The operating environment of this tutorial: windows7 system, ECMAScript version 6, Dell G3 computer.

Es6 determines whether two strings are equal.

Method 1: use the = = operator

The = = operator to compare whether the values on both sides of the equation are equal

Example: determine whether two strings are equal

Var x = "hello"; var y = "HELLO"; var z = "hello"; console.log (x = = y); / / output: falseconsole.log (x = = z); / / output: true

Method 2: use the Object.is () method

The Object.is () method determines whether two values are the same value. The two values are equal if the following conditions are met:

It's all undefined.

It's all null.

All true or false.

Are all strings of the same length and the same characters are arranged in the same order

Are all the same objects (meaning that each object has the same reference)

It's all numbers and

All + 0

All are-0

It's all NaN.

Or both are non-zero and non-NaN and have the same value

Example: determine whether two strings are equal

Var x = "hello"; var y = "HELLO"; var z = "hello"; console.log (Object.is (XMagnez)); / / output: trueconsole.log (Object.is (xmemy)); / / output: false
