The RegExp g Modifier in JavaScript is used to find all the occurrences of the pattern instead of stopping after the first match i.e it performs a global match.
Syntax:
/regexp/g
or
new RegExp("regexp", "g")
Example 1: This example searches the word “neveropen” in the whole string.
Javascript
function geek() { let str1 = "neveropen is the computer " + "science portal for neveropen." ; let regex4 = /neveropen/g; let match4 = str1.match(regex4); console.log( "Found " + match4.length + " matches: " + match4); } geek() |
Found 3 matches: neveropen,neveropen,neveropen
Example 2: This example searches the word “portal” in the whole string and replaces it with “PORTAL”.
Javascript
function geek() { let str1 = "neveropen is the computer " + "science portal for neveropen." ; let regex4 = new RegExp( "portal" , "g" ); let replace = "PORTAL" ; let match4 = str1.replace(regex4, replace); console.log( " New string: " + match4); } geek() |
New string: neveropen is the computer science PORTAL for neveropen.
