    find-token-in-code

    find a token in a code.

    (including exclude of string, comment template etc) based on find-macthing-bracket npm package

    And works for simple structure recognition in both JS Ts and Cs

        const code = `
        // test
        const foo = "test";
        let test1 = 42
        let test = true
        `;
        const position = matchToken(code, 'test');
        // position = 64 (the 'test' in 'let test = true')
        const reg_position = matchToken(code, /test\d*/);
        // reg_position = 45 (the 'test' in 'let test1 = 42')

    complex example:

        const code = "var foo = `some ${test()}`; function test(){return 0}"
        const position = matchToken(code, 'test');
        // position = 37 (the 'test' in `some ${test()}` are not alloew by default on curly;)
        // default allowed parens are  [undefined,brackets.curly]
    
        const position = matchToken(code, 'test',[undefined,brackets.curly,brackets.escapeJsTemaple]);
        // position = 18 (the 'test' in `some ${test()}`;)

    Allowed parent (Matching bracket):

    name start end node
    undefeined This is global scope
    lineComment // \n
    multilineComment /* */
    multilineComment /* */
    angle < >
    peparentheses ( )
    square [ ]
    curly { }
    double " "
    single ' '
    jsTemplate ` `
    cSharpTemplate $" "
    escapeJsTemaple ${ } only in jsTemplate
    inCSharpTemaple { } only in cSharpTemplate
