The RegExp . Metacharacter in JavaScript is used to search single characters, except line terminator or newline.
Syntax:
/regexp./
or
new RegExp("regexp.")
Syntax with modifiers:
/regexp./g
or
new RegExp("regexp.", "g")
Example 1: This example searches the words whose starting character is “A” and ending character is “C” with only one character in between them.
Javascript
function geek() { let str1 = "ABC, A3C, A C, AXXCC!"; let regex4 = /A.C/g; let match4 = str1.match(regex4); console.log("Found " + match4.length + " matches: " + match4);}geek(); |
Found 3 matches: ABC,A3C,A C
Example 2: This example searches the words having “a” as starting letter and “c” as ending the letter with only one character in between.
Javascript
function geek() { let str1 = "ABC, A3X, a x, AXXCC!"; let regex4 = new RegExp("a.x", "g"); let match4 = str1.match(regex4); console.log("Found " + match4.length + " matches: " + match4);}geek(); |
