Today, I will talk to you about how to distinguish between single quotation marks and double quotation marks in javascript. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

1. There is no difference between single quotation marks and double quotation marks, but they must be used uniformly.

2. If quotation marks are used again in quotation marks, the format of "outer double inner single" or "outer single inner double" can be adopted. Or use a backslash to escape, for example, "\", "'".

Example

/ * first initialize the string * / var str1='I love JavaScript';var str1= "I love JavaScript" with single quotation marks and double quotation marks respectively; docunment.write (str1+''); docunment.write (str2+''). After reading the above, do you have any further understanding of how to distinguish single quotation marks from double quotation marks in javascript?
