How to use String substring method In Javascript
This approach uses the substring() method to get a substring up to the specified length.
Example: This example shows the use of the above-explained approach.
// JavaScript function for
// getting a string of a
// specific length
function gfgFun(str, maxLength) {
if (str.length > maxLength) {
return str.substring(0, maxLength);
} else {
return str;
}
}
// Input String
const str = "gfg is a good place for growth";
// Desired length of a string
const maxLength = 20;
console.log(gfgFun(str, maxLength));
Output
gfg is a good place
