leftTrim

The term "leftTrim" typically refers to a function or operation in programming and data manipulation that removes whitespace characters from the beginning of a string. This process is also commonly known as "trimming" or "stripping" leading whitespace. The purpose of left trimming is to ensure that strings do not have unwanted spaces at their start, which can interfere with comparisons, parsing, or display.

Left trim functions are prevalent in most programming languages. For example, in JavaScript, the `trimStart()` method or its alias `trimLeft()` achieves this. Python offers the `lstrip()` method for strings. In Java, `trim()` removes leading and trailing whitespace, but a custom approach or a library might be needed for only left trimming. Similarly, many database systems and spreadsheet software provide functions to perform this operation on textual data.

The characters typically removed by a left trim operation include spaces, tabs, and sometimes other less common whitespace characters like newline or carriage return characters, depending on the specific implementation. The result is a new string with the leading whitespace eliminated, while the rest of the string remains unchanged. This is a fundamental string manipulation technique used to clean and standardize data.
