VS Code enforces semicolons but why doesn t Angular and TypeScript not use it consistently

0 votes

I'm taking the Microsoft Angular Fundamentals course right now and I spotted lack of semicolons in their examples, something like:

gitSearch = (query: string): Promise<GitSearch> => {
    let promise = new Promise<GitSearch>((resolve, reject) => {
        if (this.cachedValues[query]) {
            resolve(this.cachedValues[query])
        }
        else {
            this.http.get('https://api.github.com/search/repositories?q=' + query)
            .toPromise()
            .then( (response) => {
                resolve(response as GitSearch)
            }, (error) => {
                reject(error);
            })
        }
    })
    return promise;
  }

Notice they don't use semicolons after resolve.thisCachedValues[query]). But VS Code gives me TSLint warning 'Missing semicolon' at that line. Is this an issue if I omit the semicolon?

JavaScript has a syntactic feature known as semicolon insertion. Since Typescript is a strict superset of JavaScript, semicolon insertion applies to Typescript as well. This means that in most cases, semicolons are not required. You can refer the documentations for more information.
