How can I check the length of in String in JavaScript? Here is a small code example:

if(value != null && value !=  && value.length !== 10 && !value.match(/^d*$/)){



   // do something



}

The expression 'value.length !== 10' doesn´t work. A String must contain at least 10 characters. How can I solve this problem?

Instead of match, test can be used with proper regex d{10,}.

if (value && /^d{10,}$/.test(value.trim()))
