How to match a substring within 2 square brackets using RegEx in TypeScript

Answer 1

function extractBracketedContent(text: string): string[] {
    const pattern: RegExp = /\[(.*?)\]/g;
    
    const matches: string[] = [];
    let match: RegExpExecArray | null;

    while ((match = pattern.exec(text)) !== null) {
        matches.push(match[1]);
    }

    return matches;
}

const input: string = "This is a [sample] string with [multiple] square brackets.";
const extracted: string[] = extractBracketedContent(input);

extracted.forEach((item: string) => {
    console.log(item);
});

 
 
/*
run:

"sample" 
"multiple" 
     
*/
