The trim() method of String values removes whitespace from both ends of this string and returns a new string, without modifying the original string.

The indexOf() method of String values searches this string and returns the index of the first occurrence of the specified substring. It takes an optional starting position and returns the first occurrence of the specified substring at an index greater than or equal to the specified number.

The String.fromCodePoint() static method returns a string created from the specified sequence of code points.

The search() method of String values executes a search for a match between a regular expression and this string, returning the index of the first match in the string.

This page describes JavaScript's lexical grammar. JavaScript source text is just a sequence of characters — in order for the interpreter to understand it, the string has to be parsed to a more structured representation. The initial step of parsing is called lexical analysis, in which the text gets scanned from left to right and is converted into a sequence of individual, atomic input elements. Some input elements are insignificant to the interpreter, and will be stripped after this step — they include white space and comments. The others, including identifiers, keywords, literals, and punctuators (mostly operators), will be used for further syntax analysis. Line terminators and multiline comments are also syntactically insignificant, but they guide the process for automatic semicolons insertion to make certain invalid token sequences become valid.

The vector-effect property specifies the vector effect to use when drawing an object. Vector effects are applied before any of the other compositing operations, i.e., filters, masks and clips.

The JavaScript exception "invalid assignment left-hand side" occurs when there was an unexpected assignment somewhere. It may be triggered when a single = sign was used instead of == or ===.
