Frequently Asked Questions
What is String.prototype.repeat() in JavaScript?▾
"hello".repeat(3) → "hellohellohello". Added in ES6 (ES2015). It takes a count argument (non-negative integer) and throws RangeError for negative counts or Infinity. For adding a separator, use Array.from({length: n}, () => str).join(separator). Alternative: Array(n + 1).join(str) works for single characters but not multi-character strings in older code.
When is text repetition useful in development?▾
Common uses: generating filler text for UI testing ("aaaa..."), creating visual dividers ("=====" or "----"), generating test data with repeated patterns, creating ASCII art borders, padding strings to a fixed width, generating repeated HTML elements for layout testing, and creating sample data for database seeding scripts.
What is the "str_repeat" function in PHP?▾
str_repeat($str, $times) repeats a string N times. Example: str_repeat("-", 20) → "--------------------". In Python: "x" * 10 → "xxxxxxxxxx". In Go: strings.Repeat("abc", 3) → "abcabcabc". In Rust: "ha".repeat(3) → "hahaha". All modern languages provide a built-in string repeat mechanism.
How do I repeat a line N times in a shell script?▾
Bash: printf "%.0s-" {1..20} prints 20 dashes. Or: for i in $(seq 1 5); do echo "line"; done. In sed: N;P is useful for duplicating lines. Python one-liner: python3 -c "print('hello\n' * 5, end='')". printf is often the simplest: printf "text\n%.0s" {1..10}.
What are common separator patterns?▾
Common separators: newline (\n) for vertical lists, comma (,) or comma-space (, ) for CSV, pipe (|) for table columns, space for word lists, hyphen (-) or equals (=) for horizontal rules, semicolon (;) for SQL or JavaScript, tab (\t) for TSV. For no separator (concatenated output), leave separator empty.
