1. Two new methods have been added

(1) startWith: determine whether a string begins with a field

Let str='asdfgh';console.log (str.startsWith ('a')); / / true

Application:

Let str=' http://it.kaikeba.com'; If (str.startsWith ('http://')){ console.log)} else if (str.startsWith (' https://')){ console.log)} else if (str.startsWith ('git://')) {console.log ("git URL")} else if (str.startsWith (' svn://')) {console.log ("svn URL")} else { Console.log ("other URLs")}

(2) endsWith: determine whether a string ends with a field

By the same token:

Let str='asdfg.txt';if (str.endsWith ('.txt')) {console.log ("text file")} else if (str.endsWith ('.png')) {console.log ("png picture")} else if (str.endsWith ('.jpg')) {console.log ("jpg picture")} else {console.log ("other files")}

2. String template, string concatenation

(1) stuff something directly into the string

Let str1='asdfgh';// the first string method let str2='asdfgh';// the second string mode let str3= `asdfgh`; / / the third way: anti-single quotation marks / application: let axiom 12 let str4= `a ${a} bc`; console.log (str4); / / a12bc

(2) can be folded

Let title=' title'; let content=' content'; let str1='\'+ title+'\

'+ content+'

\'; let str2= `$ {title}

${content}
