Variable trim`Const`

trim: Trim = ...

String trimming utilities. Trims whitespace from a string (both sides by default) with methods for leading and trailing and normalizing whitespace.

Param: str

The string to trim.

Returns

The string with leading and trailing whitespace removed.

Remarks

The main callable form behaves like String.prototype.trim, removing whitespace from both ends.
.start removes only leading whitespace (like String.prototype.trimStart).
.end removes only trailing whitespace (like String.prototype.trimEnd).
.normalizeWhitespace trims the string and replaces any sequence of whitespace characters with a single space.

Example

// Trim both sides
console.log(trim("  hello  ")); // "hello"
console.log(trim("")); // ""
console.log(trim("hello")); // "hello"

// Trim leading whitespace
console.log(trim.start("  hello  ")); // "hello  "
console.log(trim.start("")); // ""
console.log(trim.start("hello")); // "hello"

// Trim trailing whitespace
console.log(trim.end("  hello  ")); // "  hello"
console.log(trim.end("")); // ""
console.log(trim.end("hello")); // "hello"

// Normalize whitespace
console.log(trim.normalizeWhitespace("  hello   world  ")); // "hello world"
console.log(trim.normalizeWhitespace("hello\t  world")); // "hello world"
console.log(trim.normalizeWhitespace("")); // ""
